1.0 Introduction
Congratulations on choosing the Sonic DriverTM Ultrasonic Flowmeter UFM-300,
guide-rail, pipe, wall or panel mounted clamp-on ultrasonic flowmeter, figure
(1).
Figure (1) Sonic Driver UFM-300 The UFM uses advanced Digital Signal
Processing (DSP) and transit time measurement techniques (Sonic DriverTM) to
make accurate and reliable clamp-on ultrasonic flow velocity measurements on
liquids flowing in closed pipes. Using information about the installation,
entered by the user, via the meter’s Smart phone App or laptop-based
configuration program (Windows) the UFM can calculate;
· Flow velocity (m/s) · Volumetric flow rate (l/min) · Mass flow rate (kg/min)
· Flow positive total (l) · Flow negative total (l) · Flow net total (l) When
using the Smart phone App, the meter will additionally display flow velocity
in ft/s and volumetric flow rate in m3/hr, GPM, GPH and ft3/min All the above
flow measurements and a complete set of diagnostics are available over Modbus
RTU RS485. For installation a Smart phone is connected to the UFM via a
bidirectional USB to RS485 converter. All installation parameters are
available for editing locally via the Smart phone App or remotely over Modbus
RTU.
The UFM comes in 2 different versions;
· Standard – outer pipe diameter ranged 10.0 to 115.0 mm · Medium – outer pipe
diameter ranged 115.0 to 225.0 mm
Once installed the Smart phone and converter can be disconnected and the UFM
connected to a Modbus RTU RS485 network for remote interrogation or
configuration via a control room, Cloud based monitoring applications or 3rd
party datalogger where a Modbus Master polls the UFM Slave. However, local
interrogation continues to be available by simply unplugging the network and
plugging in the Smart phone.
This manual details operating the UFM using the Smart phone configuration App
route.
A separate manual details operating the UFM using the laptop Windows
configuration program route

5.0 The User Interface
The App display consists of a standard top bar with company logo, name,
communications globe and Settings (3 vertical dots icon) top right Below the
top bar is a bar with 3 tabs; CONNECT, INSTALL and MEASURE, figure (5).
Figure (5) App display Settings gives About and Exit options. 5.1 Connect Tab
This tab shows useful information about the connection between the Smart
device and the UFM. 5.1.1 Device information Device information consists of;
· Company Name · Model Name. · Serial Number uniquely assigned during
manufacture. · Hardware and Software version numbers. 5.1.2 USB Device The
serial communication port on the Smart phone or tablet to which the UFM has
connected, for example /dev/bus/usb/002/002.
5.1.3 Test Pattern Upon successful connection the test pattern 1234.0 should appear. The following settings are designed for the UFM. They should not be changed. The ability to change the settings is intended for future product enhancements. 5.1.4 Baud Rate Default is 19200. 5.1.5 Data Bits Default is 8. 5.1.6 Parity Default is Even. 5.1.7 Stop Bits Default is 1. 5.1.8 Flow Control Default is None. 5.1.9 Slave ID Default is 1. 5.1.10 Connection Indicator This communications indicator globe will flash green when communications are taking place correctly. If communication is interrupted, then it will flash orange. 5.2 Install Tab This tab collects all the information necessary to fully install the UFM on a pipe, see figures (6). 5.2.1 Pipe Information This menu allows the user to change pipe settings, figure (6).
Figure (6) Pipe Information (Metric) By sliding the switch top right of the
screen from “mm” to “in” the entry of values can be made in imperial units or
translated into imperial units, see figure (7).
Figure (7) Pipe Information (Imperial) Other relevant values, such as sensor
spacing and fluid temperature are also converted, see figure (8).
Figure (8) Pipe Information (Imperial)
5.2.1.1 Pipe Type
The user can select the pipe material from a list;
· Carbon Steel · Stainless · Copper · PVC (Default) · Cast Iron · Ductile Iron
· HDPE
The transverse speed of sound in the pipe material is read from a database
held in the UFM.
5.2.1.2 Pipe Outer Diameter
The user is prompted to enter a value for the pipe outer diameter. Allowed
values are ranged 15.0 to 500.0 mm, default 56.0 mm.
5.2.1.3 Pipe Wall Thickness
The user is prompted to enter a value for the pipe wall thickness. Allowed
values are ranged 0.5 to 100.0 mm, default 1.8 mm.
5.2.1.4 Pipe Inner Wall Roughness
The user is prompted to enter a value for the peak to trough height of the
roughness on the inside surface of the pipe. Allowed values are ranged 0.001
to 2.00 mm, default 0.010 mm.
This value is used in flow profile correction calculations. It is unlikely the
user will change this value. Typical values are listed in the product
installation manual, Appendix B. 5.2.1.5 Number of Passes The user is prompted
to enter the number of times the sound path crosses the pipe. Allowed values
are 1 to 16 passes, the default is 6 passes. Ideally choose several passes
that results in a total path length in the fluid of 100 mm or greater.
· 1 pass, most common on large diameter pipes, sensors are on opposite sides
of the pipe. · 2 passes, the most used method, simplest to install as both
sensors are on the same side of
the pipe. · 3 passes, used on small diameter pipes. · 4 passes, used on the
lowest diameter pipes. · 5 to 15 and 16, etc. It may be that on small diameter
pipes then the recommended transducer spacing at 16 passes is not sufficient
to allow the transducers to be coupled on the same side of the pipe, an even
number of passes as they touch. In this case it is unavoidable to couple the
transducers on opposite sides of the pipe using an odd number of passes, for
example 15 passes. 5.2.2 Fluid Information This tab allows the user to change
fluid settings, figure (9).
Figure (9) Fluid Information
5.2.2.1 Type The user can select the fluid in the pipe from a list;
· Water (Default) · Petrol · Diesel · Glycol/Water The fluid longitudinal
sound velocity, kinematic viscosity and density are read from a database held
within the UFM. 5.2.2.2 Fluid Temperature The user is prompted to enter the
temperature of the fluid in the pipe. Allowed values are ranged -20 to +150
deg C, default 18 deg C. Changing Fluid Temperature causes fluid longitudinal
sound velocity, kinematic viscosity and density to be recalculated. 5.2.3
Transducer Information This menu allows the user to change transducer
settings, figure (10).
Figure (10) Transducer Information
5.2.3.1 Type
The user is prompted to select the type of sensors mounted on the pipe from a
list;
· DN40 · DM10 (Default) · DM20 · DS10
DM sensors are Sonic Driver standard PEEK/stainless steel design. DN sensors
are Sonic Driver small pipe design. DS sensors are for larger diameter pipes.
5.2.3.2 Flow Minimum Cut-Off
If the flow velocity falls below the low flow cutoff value, the measured flow
velocity and calculated flow rate indication is driven to zero. This function
can prevent the flow meter from reading flow after a pump is shut down but
there is still circulating liquid creating movement in the pipe.
Generally, 0.025 m/s is recommended 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.
The user is prompted to enter a value in m/s below which the meter reports
flow as zero. Allowed values are ranged 0.000 to 1.000 m/s, default 0.025 m/s.
Note. This absolute value is applied to both positive and negative flow as a
+/- band either side of zero.
5.2.3.3 Flow Damping
The user is prompted to enter a display damping or averaging time.
Allowed values are ranged 1 to 255 seconds, the default is 2 seconds.
The damping time can be adjusted to stabilise the flow value being displayed.
Essentially, it is a type of signal filter applying an RC time constant.
Increasing the damping increases the stability. However, the measurement
displayed can be slightly delayed due to over damping. Too much damping may
also result in no response to real time fluctuations, especially when flow
rate fluctuates wildly.
Therefore, damping should be kept at a minimum and increased just enough to
reduce the fluctuation to an acceptable degree.
5.2.4 Transducer Spacing
After entering the required parameters above, the spacing between the ends of
the 2 transducers is calculated and displayed. Check the value displayed and
space the transducers accordingly.
The Installation Manual that accompanies these Operating Instructions gives
more details regarding mounting, coupling and spacing the transducers
correctly.
5.2.5 Zero Tracking
When the measured delta time falls below a lower limit then the flow being
measured is assumed by the UFM to be zero.
The user can turn a tracking algorithm On/Off so that such a small offset
value is tracked/trended to zero.
By default, zero tracking is always turned On.
At extremely low flows the meter can mistakenly identify a flow from for
example a real leak as an erroneous offset. To avoid the leak being tracked
off turn zero tracking Off.
5.2.6 Zero Calibration
If the Zero calibration function is enabled by ticking this box, then a zero-
flow calibration will be made. It is vitally important to ensure that there is
zero flow during this procedure.
When the process is complete the user is required to untick this option.
By default, Set Zero calibration is turned Off.
NOTE. PIPE MUST BE FULL AND FLOW MUST BE ZERO.
5.3 Measure Tab
The Measurement tab shows a signal display graph, measurement values and
diagnostics, figures (9,10,11)
The UFM calculates and displays the following measurements and diagnostics
once per second.
5.3.1 Signal Display
The signal display graph is a useful diagnostic to confirm correct transducer
installation, figure (11).

Values are averaged and have flow profile compensation applied.
5.3.3 Diagnostics
Scrolling down the screen will show diagnostic values, figure (12,13).
Figure (12,13) Diagnostics
5.3.3.1 Signal Amplitude
Signal strength indicates the detected strength of the sonic signal in
decibels (dB). Signal strength is indicated by numbers from typically -25 to
+55.0.
Normally, the stronger the signal strength detected the better and more
reliable the flow measurement is, as well as the more stable the measurement
value obtained.
Adjust the transducer positioning to the best position, within limits and
check to ensure that enough sonic coupling compound is applied during
installation to obtain the maximum signal strength.
The UFM normally requires signal strength over 0.0 dB to measure reliably. If
the signal strength detected is too low (is zero or negative), the transducer
installation position and the transducer mounting spacing should be adjusted
and the pipe should be re-inspected. If necessary, change the mounting method.
5.3.3.2 Signal Noise
Noise indicates the level of extraneous sonic and electrical noise being
detected in dB. Noise is indicated by numbers from typically -25.0 to +55.0.
The UFM normally requires noise strength below +10.0 dB to measure reliably.
5.3.3.3 SNR
SNR indicates the quality of the sonic signal detected. SNR is indicated by
numbers from typically 1.0 to 99.0, in dB.
1.0 represents the minimum SNR whilst 99.0 represents the maximum.
Normally, the transducer position should be adjusted and coupling compound
application should be checked until the SNR detected is as large as possible.
The UFM normally requires SNR over 12.0 dB to measure reliably.
5.3.3.4 Amplifier Gain
Gain indicates the amount of electronic gain being used by the UFM receiver
amplifier. Gain is indicated by numbers from typically 0.0 to 81.0, in dB.
0.0 represents the minimum gain whilst 81.0 represents the maximum.
Old pipes, attenuating pipes, corrosion, attenuating fluids, etc. can require
the UFM to automatically turn up its gain.
The UFM normally operates with a gain typically around 30.0 to 60.0 dB.
5.3.3.5 Delta Time Difference
Delta Time is the difference in time between the two absolute transit times
through the fluid. Delta Time is of the order of tens of nanoseconds because
the absolute upstream and downstream times are so close together in value.
These values can help indicate the accuracy and condition of the installation.
The measurement calculations in the UFM are based upon these two values.
Therefore, when transit time difference fluctuates widely, the flow and
velocities fluctuate accordingly. This is usually accompanied by a signal
strength and/or signal to noise ratio (SNR) that is too low and varying. This
may be the result of poor pipe installation conditions, inadequate transducer
installation, or incorrect parameter input. Generally, fluctuations should be
less than ± 20 %.
5.3.3.6 Upstream Transit Time
The absolute upstream transit time through the fluid in the pipe and the
absolute downstream transit time through the fluid in the pipe are usually of
the order of hundreds of microseconds. They are very nearly identical. For
this reason, transit time is simply displaying the absolute upstream transit
time through the fluid in the pipe.
5.3.3.7 Delta Time Offset
dT Offset is the offset value currently being used by the zero-tracking
function. This is usually in the range ± 2.5 ns.
5.3.3.8 ATA/ETA
This is a measure of the ratio of the measured transit time to that which is
expected given the parameters entered by the user during installation. It
indicates if the transducer mounting and spacing is accurate. The normal
transit time ratio should be 100 ± 3 % if the installation is correct.
It is acceptable to have to move one of the transducers up to ± 5mm to achieve
a figure of 100 %. If more movement is necessary, then one of the pipe
parameters is probably incorrect. This is most likely to be the value entered
for pipe wall thickness as this is often taken from tables or it is an
estimated value. 5.3.4 Totaliser At the bottom of the Measure Tab it is
possible to; START, STOP and RESET the totaliser within the UFM in units of
litres, see figure (14).
