Installation and Wiring

4.1 Installation Description

1. Carefully read “Section 7. Choose Measurement Point”. After the designated location is selected, the area outside the pipe to be installed must be cleaned, and the dense part of the pipe is more appropriate for installation.
2. The special coupling sticker of the company is pasted on the center of the sensor, which will be squeezed during installation to ensure that the sensor and the pipe wall are closely fitted without bubbles. It comes with coupling compound and replaceable coupling pads. The coupling compound can be applied to the coupling pads.
3. The direction of the arrow on the nameplate of the instrument must be consistent with the direction of the fluid in the pipeline.

Measurement Site Selection

The flowmeter is simple and convenient to install. As long as a suitable measuring point is selected, Clamp the product sensor surface on the pipe section directly and fix the pipe clamp, and then the power is turned on, the flow measurement can be realized.
When selecting measuring points, it is required to select pipe sections with uniform fluid flow field distribution to ensure measurement accuracy. The following principles shall be followed during installation:

• Select a pipe segment that is filled with fluid, such as the vertical part of the pipe line (the fluid is better to flow upward) or the horizontal pipe segment that is filled with fluid.
• The measuring point should be on a uniform straight pipe section with 10 times the diameter (10D) from the upstream and 5 times the diameter (5D) from the downstream. There are no valves, elbows, reducers and other devices interfering with the flow field within this range. The length of the straight pipe section is recommended to use the values shown in the following table.
• Ensure that the temperature at the measuring point is within the working range.
• Fully consider the scaling condition on the inner wall of the pipe, try to select the pipe section without scaling for measurement, and select the pipe section of uniform and dense pipes so as to make ultrasonic transmission easier.

Communication Protocol

The flow meter adopts the response communication method, the upper computer to send “command” way, ask the lower position flow meter to response. The asynchronous communication baud rate (main workstation, computer system, ultrasonic flow meter) is generally 9600bps. Single byte data format (10 bits): 1 start bit, 1 stop bit and 8 data bits. Check bit: NONE.

8.1 FUJI Protocol
The FUJI protocol of the meter adopts the response communication mode, and the upper system requests the meter to response by issuing “commands”. The asynchronous communication baud rate (main workstation, computer system, secondary workstation, ultrasonic flow meter) is usually 9600bps. Single byte data format (10bits): 1 starting bits, 1 stop bits and 8 data bits. Check bit: NONE.
The basic commands are represented by data strings and the end of the command is indicated by a carriage return line break.They are characterized by arbitrary data length. The commands commonly used are shown in the following table:

Communication command

Bit Length
DL(cr) (lf)| Return signal strength| UP:dd.d，DN:dd.d，Q=dd(cr)
ESN(cr) (lf)| Return electronic serial number| ddddddd(cr)(lf) Note3
W| Digital string address network command prefix| Note 4
P| Prefix with checksum return command|
&| Command “plus” function symbol|

Note：

1. (cr)indicates carriage return，Its ASCII value is 0DH.(lf) indicates a line feed and its ASCII value is 0AH.

2. d is a number ranging from 0 to 9, 0 value is indicated as+0.000000E+00.
   d is a number ranging from 0 to 9, the integer part in front of “E” has no decimal point.

3. dddddddd eight digits indicate the electronic serial number of the machine, t indicates the machine code.

4. If there are multiple traffic tables in the data network at the same time, the basic command cannot be used alone, and must be prefixed with W before it can be used, otherwise it will cause multiple traffic tables to response at the same time, which may result in system confusion.

（1）P prefix
Character P can be added before each basic command to indicate that the returned data has CRC verification.The check sum is obtained by binary addition.
For example: If the return data of the command DI+ (CR)(The corresponding binary data are 44H, 49H, 2BH, 0DH)is+1234567E+0m3 (CR)(The corresponding binary data are 2BH，31H，32H，33H，34H，35H， 36H，37H，45H，2BH，30H，6DH，33H，20H，0DH，0AH) the return data of the command PDI+ (CR) is +1234567E+0m3 !F7 (CR). “!” indicates that it is a sum character in front of it, and the checksum of two bytes is in the back (2BH+31H+32H+33H+34H+35H+ 36H+37H+45H+2BH+30H+6DH+33H+20H=(2)F7H).
Note that “!” can be preceded by no data, and a space character may be present.
（2）W prefix
The usage of W prefix: W + string address code(Must be 5-digit number) + basic command, digital string value range 0~65535 except 13 (0DH enter), 10(0AH line feed) 42(2AH*), 38(26H&). If access to the instantaneous flow rate of the flow meter No. 12345, issue the command W012345DV (CR), the corresponding binary codes are 57H，31H，32H，33H，34H，35H，44H，56H，0DH.
（3） &Functional symbols
& the function symbol can add up to five basic commands (prefixed with P) to form a composite command and transmit it to the flow meter, which responds at the same time. For example, to send back simultaneously 1.
instantaneous flow rate; 2. instantaneous flow rate; 3. positive cumulative quantity; 4. negative cumulative quantity; and 5. net cumulative quantity with verification from the flow meter No. 4321, send the command as follows:

W04321PDQD &PDV&PDI+&PDI-&PDIN（CR）
The data returned at the same time may be as follows:
+0.000000E+00m3/d! AC（CR）
+0.000000E+00m/s! 88（CR）
+1234567E+0m3! F7（CR）
+0.000000E+0m3! DA（CR）
+0.000000E+0 m3! DA（CR）

8.2 MODBUS Communication Protocol

The MODBUS protocol of this instrument adopts RTU transmission mode, and its check code is obtained by CRC-16-IBM (polynomial is X16+X15+X2+1, shielded word is 0xA001) cyclic redundancy algorithm.
MODBUS RTU mode uses hexadecimal to transmit data.
8.2.1 MODBUS protocol function code and format
This instrument protocol supports the following two function codes of MODBUS protocol:

8.2.2 Use of MODBUS protocol function code 0x03
Format of read register information frame sent by the host:

Slave address| Function code| Register first address| Number of registers| Check code
---|---|---|---|---
1 bytes| 1 bytes| 2 bytes| 2 bytes| 2 bytes
0x01~0xF7| 0x03| 0x0000~0xFFFF| 0x0000~0x7D| CRC check code

Slave retumed data frame format:

Slave address| Read operation function code| Number of bytes of data| Data| Check code
---|---|---|---|---
1 bytes| 1 bytes| 1 bytes| Nx2 bytes| 2 bytes
0x01~0xF7| 0x03| 2xN| N*x2data| CRC check code

N＝Number of registers for data.
The value range of instrument address (address of flowmeter) is 1~247 (hexadecimal: 0x01~0xF7), and the address can be viewed in Menu 46. If the decimal number displayed in Menu 46 is 11, the address of this instrument in MODBUS protocol is 0x0B.
The CRC check code of this instrument is obtained by using CRC-16-IBM (polynomial is X16+X15+X2+1, shielded word is 0xA001) cyclic redundancy algorithm. The low byte of the check code comes first and the high byte comes last.
Example 1. In RTU mode, read the instantaneous flow (m3/h) of the meter with address 1 (0x01) in hours, that is, read the data of registers 40,005 and 40,006. The read command is as follows:
0x01 0x03 0x00 0x04 0x00 0x02 0x85 0xCA

Please note the order of data storage in the above example. When using C language to interpret values, users can use pointers to directly put the required data into the corresponding variable address. The general order of storage is that low byte comes first. For example, in the 1.2,345,678m/s example above, the storage order of data 3F 9E 06 51 is 06 51 3F 9E.
Example 2. In RTU mode, read the positive cumulative flow (m3) in m3 of the instrument with address 1
(0x01), that is, read the data of three registers with register addresses 0008, 0009 and 000A. The read command is as follows:
0x01 0x03 0x00 0x08
0x00 0x03 0x84 0x09
Instrument Address Function Code Register First Address Register Number CRC Check Code The data returned by the instrument is (assuming the current positive cumulative flow=2.46m3):

8.2.3 Error Handling
This instrument returns only one error code 0x02, indicating that the first address of the data is wrong.
For example, in RTU mode, only 40002 register data of the instrument with address 1 (0x01) is read. The instrument thinks that the integrity of the data is damaged, and the command sent is:
