l Ensure enough straight pipe length at least equal to the figure shown below for the upstream and downstream transducers installation. Try to avoid Ensure enough straight pipe length at least equal to the figure shown below for the upstream and downstream transducers installation.
l On the horizontal pipe, the transducer should be mounted on the 9 and 3 of the pipe, avoiding the position of 6 and 12, in case of the signal attenuation caused by pipe at the bottom sediment or bubblecavitation on the pipe.
l Ensure that the measuring site temperature is under the transducer temperature limits. l Consider the inside condition of the pipe carefully. If possible, select a section of pipe where the inside is free
of excessive corrosion or scaling. l Choose a section of sound conducting pipe.

4.Transducer Installation

4.1. Transducer Installation
Please make sure the pipe surfaces where the transducers are to be mounted are all clean. Including the rust, scale or loose paint to have a smooth surface. Choose the section and don’t forget apply the coupling compound. Apply the coupling compound down the center of the face of each transducer as well as on the pipe surface, ensure there are no air bubbles between the transducers and the pipe wall, and then attach the transducers to the pipe with the straps provided and tighten them securely.
Note: The two transducers should be mounted at the pipe’s centerline on horizontal pipes.
Make sure that the transducer mounting direction is parallel with the flow.
During the installation, there should be no air bubbles or particles between the transducer and the pipe wall. On horizontal pipes, the transducers should be mounted in the 3 o’clock and 9 o’clock positions of the pipe section in order to avoid any air bubbles inside the top portion of the pipe. (Refer to Transducer Mounting). If the transducers cannot be mounted horizontally symmetrically due to limitation of the local installation conditions, it may be necessary to mount the transducers at a location where there is a guaranteed full pipe condition (the pipe is always full of liquid).
4.1.1. Transducer Spacing

The spacing between the ENDS of the two transducers is considered as the standard transducer spacing (Refer to MENU14). After entering the required parameters, Check the data displayed in Window M14 and adjusted the transducers spacing according to the data displayed in Windows M14.
1.1.2 Transducer Mounting Methods

There are two mounting method, you could use depend on the measuring environment. V method and Z method (Reflect method and Direct method). V method is easy to installation and fit for mostly ultrasonic environment but Z method has stronger signal and works better in the complicated measuring environment.
4.1.3. V Method

The V method is considered as the standard method. It is convenient to use, but still requires proper installation of the transducers, contact on the pipe at the pipe’s centerline and equal spacing on either side of the centerline.

4.1.4. Z Method

The signal transmitted in a Z method installation has less attenuation than a signal transmitted with the V method
When the pipes are too large, there are some suspended solid in the fluid, or the scaling and liner are too thick. This is because the Z method utilizes a directly transmitted (rather than reflected) signaling which transverses the liquid only once. The Z method is able to measure on pipe diameters ranging from 100mm to 5000mm (4 inch to 200 inch) approximately. Therefore, we recommend the Z method for pipe diameters over 300mm (12 inch).

4.2. Transducer Mounting Inspection
Check to see if the transducer is installed properly and if there is an accurate and strong enough ultrasonic signal

Ultrasonic Heatmeter Operation Manual
to ensure proper operation and high reliability of the transducer. It can be confirmed by checking the detected signal strength, total transit time, delta time as well as transit time ratio. The “mounting” condition directly influences the flow value accuracy and system long-time running reliability. In most instances, only apply a wide band of sonic coupling compound lengthwise on the face of the transducer and stick it to the outside pipe wall to get good measurement results. However, the following inspections still need to be carried out in order to ensure the high reliability of the measurement and long-term operation of the instrument.
4.2.1. Signal Strength
Signal strength (displayed in Window M04) indicates a detected strength of the signal both from upstream and downstream directions. The relevant signal strength is indicated by numbers from 00.0 ~ 99.9. 00.0 represents no signal detected while 99.9 represent maximum signal strength. Normally, the stronger the signal strength detected, the longer the operation of the instrument reliably, as well as the more stable the measurement value obtained. Adjust the transducer to the best position and check to ensure that enough sonic coupling compounds is applied adequately during installation in order to obtain the maximum signal strength. System normally requires signal strength over 75.0, which is detected from both upstream and downstream directions. If the signal strength detected is too low, the transducer installation position and the transducer mounting spacing should be re-adjusted and the pipe should be re-inspected. If necessary, change the mounting method to be Z method.
4.2.2. Signal Quality (Q value)
Q value is short for Signal Quality (displayed in Window M04). It indicates the level of the signal detected. Q value is indicated by numbers from 00 ~ 99. 00 represents the minimum signal detected while 99 represent the maximum. Normally, the transducer position should be adjusted repeatedly and coupling compound application should be checked frequently until the signal quality detected is as strong as possible.
4.2.3. Total Time and Delta Time
“Total Time and Delta Time”, which displays in Window M04, indicates the condition of the installation. The measurement calculations in the Flow meter are based upon these two parameters. Therefore, when “Delta Time” fluctuates widely, the flow and velocities fluctuate accordingly, this means that the signal quality detected is too poor. It may be the resulted of poor pipe- installation conditions, inadequate transducer installation or incorrect parameter input.
Generally, “Delta Time” fluctuation should be less than ±20%. Only when the pipe diameter is too small or
velocity is too low can the fluctuation be wider.
4.2.4. Transit Time Ratio
Transit Time Ratio indicates if the transducer mounting spacing is accurate. The normal transit time ratio should be 100+/-3 if the installation is proper. Check it in Window M04.
Attention
If the transit time ratio is over 100± 3%, it is necessary to check:
(1) If the parameters (pipe outside diameter, wall thickness, pipe material, liner, etc.) have been entered correctly,
(2) If the transducer mounting spacing is accordance with the display in Window M14, (3) If the transducer is mounted at the pipe’s centerline on the same diameter, (4) If the scale is too thick or the pipe mounting is distorted in shape, etc.

Ultrasonic Heatmeter Operation Manual
4.2.5. Warnings
(1) Pipe parameters entered must be accurate; otherwise the Flow meter will not work properly. (2) During the installation, apply enough coupling compounds in order to stick the transducers onto the
pipe wall. While checking the signal strength and Q value, move the transducers slowly around the mounting site until the strongest signal and maximum Q value can be obtained. Make sure that the larger the pipe diameter, the more the transducers should be moved. (3) Check to be sure the mounting spacing is accordance with the display in Window M14 and the transducer is mounted at the pipe’s centerline on the same diameter. (4) Pay special attention to those pipes that formed by steel rolls (pipe with seams), since such pipe is always irregular. If the signal strength is always displayed as 0.00, that means there is no signal detected. Thus, it is necessary to check that the parameters (including all the pipe parameters) have been entered accurately. Check to be sure the transducer mounting method has been selected properly, the pipe is not worn-out, and the liner is not too thick. Make sure there is indeed fluid in the pipe or the transducer is not too close to a valve or elbow, and there are not too many air bubbles in the fluid, etc. With the exception of these reasons, if there is still no signal detected, the measurement site has to be changed. (5) Make sure that the Flow meter is able to run properly with high reliability. The stronger the signal strength displayed, the higher the Q value reached. The longer the Flow meter runs accurately, the higher the reliability of the flow rates displayed. If there is interference from ambient electromagnetic waves or the signal detected is too poor, the flow value displayed is not reliable; consequently, the capability for reliable operation is reduced. (6) After the installation is complete, power on the instrument and check the result accordingly.

Ultrasonic Heatmeter Operation Manual
5.Operating Instructions
5.1. System Normal Identification
If the letter “*R” displays on the screen, it indicates system normal. If the letter “D” is displayed, it indicates that system is adjusting the signal gain prior to the measurement. Also, it means system normal. Only when the adjustment takes too long without stopping, can system be identified as abnormal. Letter “E” indicates no signal is being detected. Check the transducer wiring connections are correct, the transducers are installed firmly, etc. For further information, please refer to “Error Diagnosis”.
5.2. Low Flow Cutoff Value
The data in M21 is Low Flow Cutoff Value. If the flow rate falls below the low flow cutoff value, the flow indication is driven to zero. This function can prevent the flow meter from displaying flow as “0”after a pump was shut down, but there is still liquid movement in the pipe, which will result in cumulative error. Generally, 0.03m/s is recommended to enter as the low flow cutoff point. The low flow cutoff value has no relation to the measurement results once the velocity increases over the low flow cutoff value.
5.3. Zero Settings
Once zero flow occurs, a zero point may indicate on each measuring instrument, but the displayed measuring value is not equal to “0”, this value indicates “Zero”. To any measuring instrument, the smaller the “Zero” is, the better the quality is. Conversely, if the Zero is too big, that indicates the quality of the instrument is poor. If the zero set point is not at true zero flow, a measurement difference may occur. The smaller the physical measurement capacity is, the larger the measurement difference from the zero point will exist. Only when zero point reduced to a definite degree, as compared with the physical measurement capacity, can the measuring difference from zero point be ignored. For an ultrasonic Flow meter, the measurement error from zero point cannot be ignored under low flow conditions. It is necessary to perform a static zero set calibration to improve low flow measurement accuracy. Cutoff Zero In Window M22- Cutoff- 1.Yes, window will show the “success” and back to M01 when you cut off the zero point successfully. Performing Set Zero In Window M22- Reset
5.4. Scale Factor
Scale factor refers to the ratio between “actual value” and “reading value”. For example, when the measurement is 2.00, and it is indicated as 1.98 on the instrument, the scale factor reading is 2/1.98. This means that the best scale factor constant is 1. However, it is difficult to keep the scale factor as “1” on the instrument especially in batch productions. The difference is called “consistency”. During operation, there still exists possible difference in pipe parameters, etc. The “scale factor” may be necessary when used on different pipes. Thus, scale factor calibration is specially designed for calibrating the differences that result from application on different pipes. The scale factor entered must be one that results from actual flow calibration. The scale factor can be input in Window M26.

5.5. System Lock
System lock is intended to prevent operation error due to tampering by unauthorized personnel. M54 is for system lock, unlock it by using the selected password only. If “lock” is displayed on the screen, then enter the correct password. Keep the password in mind or recorded in a safe place, otherwise the instrument cannot be used.
5.6. 4 ~ 20mA Current Loop Output
With a current loop output exceeding an accuracy of 0.1%, the flow meter is programmable and configurable with outputs such as 4 ~ 20mA or 0 ~ 20mA selected in Menu 32. For details, please refer to Menu 32 in “Window Display Explanations”. In Window M32- Range- LowL, enter a 4mA flow value. Enter the 20mA flow value in Window M32Range-UpperL. For example, if the flow range in a specific pipe is 0 ~ 1000m3/h, enter 0 in Window M32 and 1000 in Window M32. If the flow ranges from -1000 ~ 0 ~ 2000m3/h, configure the 20 ~ 4 ~ 20mA output by selecting in Window M32 when flow direction is not an issue. Enter 1000 in Window M32 LowL and 2000 in Window M32 UpperL. When flow direction is an issue, module 0 ~ 4 ~ 20mA is available. When the flow direction displays as negative, the current output is in range of 0 ~ 4mA, whereas the 4 ~ 20mA is for the positive direction. The output module options are displayed in Window M32. Calibrating and testing the current loop is performed in Window M32-Check. Complete the steps as follows: Use “” and “” to switch. “check 4mA”, “check 8mA”, “check 16mA”, “check 20mA” readings, connect an ammeter to test the current loop output and calculate the difference. Calibrate the 4-20mA is in M62.
5.7. Frequency Output
The flow meter is provided with a frequency output transmitter function. The high or low frequency output displayed indicates the high or low flow rate reading. The user can reset the frequency output as well as flow rate as the user’s actual requirements. For example: if a pipe flow range is 0 ~ 5000m3/h, the relative frequency output required is 100 ~ 1000Hz, and the configuration is as follows: In Window M33-Range-LowerL (lower limit frequency output flow value), input 0; In Window M33-Range -UpperL (upper limit frequency output flow value), input 5000; In Window M33-Mode-Frange( frequency range), input 1001000; In Window M33-Mode-Option, select “a.Flow Rate”; Typical OCT Output wiring diagram as below:

Ultrasonic Heatmeter Operation Manual
5.8. Totalizer Pulse Output
Each time the flow meter reaches a unit flow, it may generate a totalizer pulse output to a remote counter. The totalizer pulse output can be transmitted through OCT or a relay. Therefore, it is necessary to configure OCT and the relay accordingly. (Please refer to Window M33 and M34). For example, if it is necessary to transmit the positive totalizer pulse through a relay, and each pulse represents a flow of 10m3, the configuration is as follows: In Window M41-Unit, select the totalizer flow unit “m3”; In Window M41-MULT, select the scale factor “e. x10”; In Window M34-Option, select “g. POS Total “;
Attention Make sure to select an appropriate totalizer pulse. If the totalizer pulse is too big, the output cycle will be too long; if the totalizer is too small, the relay will operate too faster, you may shorten the life of the relay, as well as skip some pulses. The totalizer is recommended to transmit within the range of 1 ~ 3 pulse per second.
5.9. Alarm Programming
The on-off output alarm is generated through OCT or transmission to an external circuit by opening or closing a relay. The on-off output signal is activated under the following conditions:
(1) Signal not detected; (2) Poor signal detected; (3) The flow meter is not ready for normal measurement; (4) The flow is in the reverse direction (back flow). (5) The analog outputs exceed span by 120%. (6) The frequency output exceeds span by 120%. (7) The flow rate exceeds the ranges configured (Configure the flow ranges using the software alarm system.
There are two software alarms: Alarm#1 and Alarm #2. Example 1: When flow rate exceeds 300 ~ 1000 m3/h, in order to program the relay output alarm, Complete the steps as follows:
(1) In Menu 35, Alarm1 LowL 300; (2) In Menu 35, Alarm1 Upper 1000; (3) In Menu 34, Relay Setting-Option-d.Alarm1
5.10.4-20mA Analog Output Calibration
Attention Each flow meter has been calibrated strictly before leaving factory. It is unnecessary to carry out this step except when the current value (detected while calibrating the current loop) displayed in Window M32 is not identical with the actual output current value.
The hardware detect window must be activated prior to calibration the Analog Output. The procedure is as follows: Menu 62 is for 4-20mA calibration, if you need enter the pass word to enter. With no effect to next power on, this window will close automatically as soon as the power is turned off. Use “” and “” to switch. Calibrate the current loop 4mA output. Use an ammeter to measure the output current of current loop and adjust the displayed numbers at the same time. Watch the ammeter until it reads 4.00.

Status Display the Signal strength, the Upstream signal strength and Downstream signal strength. Signal quality Q is indicated by 00 ~ 99. Therefore, 00 indicates the poorest signal while 99 indicates the best signal. Normally, signal quality Q value should be better than 60
Display the measured fluid sound velocity. Normally this value should be approximately equal to the entered value in Window M12. If the difference is too large, it probably results from an incorrect value entered in Window M12 or improper installation of the transducers. Display the ratio between the actual measured transmit time and the calculated transmit time according to customer’s requirement. Normally the ratio should be 100±3. If the difference is too large, the user should check that the parameters are entered correctly, especially the sound velocity of the fluid and the installation of the transducers. This data is of no use before the system is ready. Display the measured ultrasonic average time (unit: us) and delta time of the upstream and downstream (unit: ns) time. The velocity calculation in the flow meter is based on the two readings. The delta time is the best indication that the instrument is running steadily. Normally the fluctuation in the ratio of the delta time should be lower than 20%. If it is not, it is necessary to check if the transducers are installed properly or if the parameters have been entered correctly.

Damping The damping factor ranges from 1 ~ 999 seconds.1 indicates no damping; 999 indicates the maximum damping. The damping function will stabilize the flow display. Usually a damping factor of 3 to 10 is recommended in applications.
M21
Low Vel. Cut off Low Flow Cut off is used to make the system display as “0” value at lower and smaller flows to avoid any invalid totalizing. For example, if the cutoff value is set as 0.03, system will take all the measured flow velocity values from – 0.03 to + 0.03 as “0”. Generally, 0.03 is recommended in most applications.

M22
Zero Settings When fluid is in the static state, the displayed value is called “Zero Point”. When “Zero Point’ is not at zero in the flow meter, the difference is going to be added into the actual flow values and measurement differences will occur in the flow meter. Set zero must be carried out after the transducers are installed and the flow inside the pipe is in the absolute static state (no liquid movement in the pipe). Thus, the “Zero Point” resulting from different pipe mounting locations and parameters can be eliminated. The measuring accuracy at low flow is enhanced by doing this and flow offset is eliminated.
Select “YES”; reset “Zero Point” which was set by the user.
This method is not commonly used. It is only suitable for experienced operators to set zero under conditions when it is not preferable to use other methods. Enter the value manually to add to the measured value to obtain the actual value. For example: Actual measured value 240 m3/H Value Deviation 10 m3/H Flow meter Display 250 m3/H Normally, set the value as “0”. Use “” and “” to switch.

7. Error Diagnoses

The ultrasonic flow meter has advanced self-diagnostics functions and displays any errors in the upper right corner of the LCD via definite codes in a date/time order. Some errors can be detected during normal operation. Undetectable errors caused by unskilled operation, incorrect settings and unsuitable measurement conditions can be displayed accordingly during work. This function helps the user detect the errors and find causes quickly; thus, problems can be solved in a timely manner according to the solutions listed in the following table.
If a problem still exists, please contact the factory or the factory’s local representative for assistance.

Causes

Solutions

System normal.
Signal not detected.
Spacing is not correct between the transducers or not enough coupling compound applied to face of transducers.
Transducers installed improperly.
Scale is too thick.
New pipe liner.
Attach transducer to the pipe and tighten it securely. Apply a plenty of coupling compound on transducer and pipe wall.
Remove any rust, scale, or loose paint from the pipe surface. Clean it with a file.
Check the initial parameter settings.
Remove the scale or change the scaled pipe section. Normally, it is possible to change a measurement location. The instrument may run properly at a new site with less scale.
Wait until liners solidified and saturated.
Adjusting gain for normal measurement.

Ultrasonic Heatmeter Operation Manual

7.2. Frequently Asked Questions and Answers
Question: New pipe, high quality material, and all installation requirements met: why still no signal detected?
Answer: Check pipe parameter settings, installation method and wiring connections. Confirm if the coupling compound is applied adequately, the pipe is full of liquid, transducer spacing agrees with the screen readings and the transducers are installed in the right direction.

Question: Old pipe with heavy scale inside, no signal or poor signal detected: how can it be resolved?

Answer:

Check if the pipe is full of fluid. Try the Z method for transducer installation (If the pipe is too close to a wall, or it is necessary to install the transducers on a vertical or inclined pipe with flow upwards instead of on a horizontal pipe).
Carefully select a good pipe section and fully clean it, apply a wide band of coupling compound on each transducer face (bottom) and install the transducer properly.
Slowly and slightly move each transducer with respect to each other around the installation point until the maximum signal is detected. Be careful that the new installation location is free of scale inside the pipe and that the pipe is concentric (not distorted) so that the sound waves do not bounce outside of the proposed area.
For pipe with thick scale inside or outside, try to clean the scale off, if it is accessible from the inside. (Note: Sometimes this method might not work and sound wave transmission is not possible because of the a layer of scale between the transducers and pipe inside wall).

Question: Why is the CL output abnormal?
Answer: Check to see if the desired current output mode is set in Window M32-Mode. Check to see if the maximum and minimum current values are set properly in Windows M32-Range. Re-calibrate CL and verify it in Window M32-Check.

Question: Why is the flow rate still displayed as zero while there is fluid obviously inside the pipe and a symbol of “R” displayed on the screen?
Answer: Check to see if “Set Zero” was carried out with fluid flowing inside the pipe (Refer to Window M22). If it is confirmed, recover the factory default in Window M22-Reset.

8. Appendix 3 Serial Interface Network Use and Communications Protocol

8.1. Overview

The flow meter has perfect communication protocol. It can also be connected to a RS-485 Modbus .
Two basic schemes can be chosen for networking, i.e. the analog current output method only using the flow meter or the RS232 communication method via serial port directly from the flow meter. This method is suitable to replace dated instruments in old monitoring networks. The later method is used in new monitoring network systems. It has advantages include low hardware investment and reliable system operation.
When the serial port communications method is directly used to implement a monitoring network system, the address identification code of the flow meter is used as a network address code. Expanded command set with [W] is used as communication protocol.
RS-232 (Cable length 0 ~ 15m ) or RS-485 ( cable length 0 ~ 1000m ) can be directly used for data transmission links for a short distance. Current loop can be used in medium or long distance transmission.
When the flow meter is used in a network environment, various operations can be performed by a host device, except for programming of the address identification code, which needs to be done via the flow meter keyboard.
The command answer mode is used in data transmission, i.e. the host device issues commands and the flow meter answers correspondingly.
Common/special flow / thermal data monitoring system developed by our company can be used for flow data collection. Based on characteristics of the flow meter, the system makes full use of software and hardware designs with flow meter features. The system is simple, clear, economical, and reliable in operation.
Attention
In the communication protocol used functions, RS232 and RS485 serial communications cannot be used at the same time.
8.2. Serial port definitions

Ultrasonic Heatmeter Operation Manual
8.3. Direct connection via RS232 to the host device
See the below list of flowmeter serial port definitions.

8.4. Communications protocol and the use

The flow meter supports these three communication protocols: FUJI Protocol, MODBUS-C Protocol, MODBUS-I Protocol.
8.4.1. HL Protocol

The communication protocol format used by the ultrasonic flow meter is an expanded set of the HL FLV series flow meter protocol. The host device requests the flow meter to answer by sending a “command”. The baud rate of asynchronous communication (Primary station: computer system; Secondary station: ultrasonic flow meter) is generally 9600BPS. A single byte data format (10 bits): one start bit, one stop bit and 8 data bits. Check bit: none.
A data character string is used to express basic commands and a carriage return (ENTER) is used to express the end of a command. The characteristic is that the string of data is flexible. The order applies to both RS232 and RS485. Frequently used commands are as follows:
Communications commands

Prefix of return command with check

Note 5

W

Networking command prefix of numeric string address

Note 6

Note:
1.(cr)expresses carriage return. Its ASCII value is 0DH. (lf) expresses line feed. Its ASCII value is 0AH.
2.”d” expresses 0-9 number. 0 value is expressed as +0.000000E+00.
3.”d” expresses 0-9 numbers. There is no decimal point in integral part before “E”.
4. dddddddd means the serial number of the instrument, t means the model of the instrument.
5. The character P can be added before every basic command. It means that the transferred data has CRC verification. The method of verification is to add all of the data back to the data, which is cumulative and binary, and its low 8-bit binary data is taken.
E.g. The return information of the RT(cr)(lf) is :+1234567E+0m3(cr)(lf), (the relative binary system data is 2BH31H32H33H34H35H36H37H45H2BH30H6DH33H20H0DH

0AH) The sum of all of its return data is =2BH+31H+32H+33H+34H+35H+ 36H+37H+45H+2BH+30H+6DH+33H+20H=2F7, The low 8-bit data of its binary is F7.
Therefore, the data of the order PRT (cr) (lf) is called + 1234567E + 0m3!F7 (cr) (lf), “!”For delimiters, the preceding is the character of the summation, followed by a check code of 1 byte.
6.Usage of prefix W: W+ numeric string address code +basic command. Value range of the numeric string is 0 ~ 255, except 13 (0DH carriage return ), 10 ( 0AH line feed ). If the instantaneous velocity of No. 123 flow meter is to be accessed, the command W123DV (cr)(lf) can be issued. The corresponding binary code is 57H, 31H, 32H, 33H, 44H, 56H, 0DH, 0AH, only the same instrument with the same address of the Internet address and command will send back the data.
7.W and P commands can be used in combination, for example, W123PRT +, which means that the instrument that reads the network address is the cumulative value of the instrument with 123, and its return data has eight accumulations and checksums.”s” expresses ON or OFF or UD. For example, “TR:ON, RL:ON” expresses that the OCT and relay are in an actuated status; “TR:UDRL:UD” expresses that the OCT and relay are not actuated.

This MODBUS-I Protocol uses RTU transmission mode. The Verification Code uses CRC-16-IBM (polynomial is X16+X15+X2+1, shield character is 0xA001) which is gained by the cyclic redundancy algorithm method. MODBUS-I RTU mode uses hexadecimals to transmit data.
1. MODBUS-I Protocol Function Code and Format The flow meter protocol supports the following two-function codes of the MODBUS:

Function Code

Performance data

0x03

0x0000 ~ 0xFFFF CRC ( Verify )

The range of flow meter addresses 1 to 247 (Hexadecimal: 0x01 ~ 0xF7 ), and can be checked in the Menu 46. For example, decimal number “11” displayed on Menu 46 means the address of the flow meter in the MODBUS protocol is 0x0B.
The CRC Verify Code adopts CRC-16-IBM (polynomial is X16+X15+X2+1, shield character is 0xA001) which is gained by the cyclic redundancy algorithm method. Low byte of the verify code is at the beginning while the high byte is at the end.

For example, to read the address 1 (0x01) in the RTU mode, if the instantaneous flow rate uses hour as a unit m3/h, namely reads 40005 and 40006 registers data, the read command is as follows:

0x01

0x03

0x00 0x04

The four bytes 3F 9E 06 51 is in the IEEE754 format single precision floating point form of 1.2345678.

Pay attention to the data storage order of the above example. Using C language to explain the data, pointers can be used directly to input the required data in the corresponding variable address, the low byte will be put at the beginning, such as the above example 1.2345678 m/s, 3F 9E 06 51 data stored in order as 51 06 9E 3F.

For example, it converts the address 1 (0x01) to 20x02under the RTU mode, so to write the data of flowmeter 44100 register as 0x02, the write command is as follows:

0x01

0x06

0x10 0x03

4. Error Check

The flow meter only returns one error code 0x02 which means data first address in error.

Ultrasonic Heatmeter Operation Manual

For example, to read address 1 (0x01) of the flow meter 40002 register data in the RTU mode, the flow meter considers it to be invalid data, and sends the following command:
