Page 3: Introduction
Congratulations on choosing the Sonic Driver Ultrasonic Flowmeter UFM-300, guide-rail, pipe, wall or panel mounted clamp-on ultrasonic flowmeter, figure (1). Figure (1) The Sonic Driver UFM-300. The UFM uses advanced Digital Signal Processing (DSP) and transit time measurement techniques (Sonic Driver ) to make accurate and reliable clamp-on ultrasonic flow velocity measurements on liquids flowing in closed pipes. - Page 4 For installation a laptop is connected to the UFM via a bidirectional USB to RS485 converter. All installation parameters are available for editing locally via the laptop or remotely over Modbus RTU. The UFM comes in 2 different versions; • Standard - outer pipe diameter ranged 10.0 to 115.0 mm •...

Page 6: Configuration Program Functionality
2.0 Configuration Program Functionality The UFM is installed and commissioned using the Configuration Program installed and running on a laptop (Windows). Read the Installation manual for instructions on installing the Configuration program. The Configuration program is basically a dashboard, see figure (2) which includes sections for; •... -
Page 7: Quick Start
2.1 Quick Start This section, on the left-hand side of the dashboard, takes the user through a sequence of configuring the basic parameters necessary to get the UFM measuring reliably and accurately, see figure (3). Figure (3) Quick Start Section. Parameters and settings in the UFM can be edited by;... -
Page 8: Transducer Type
• 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 large diameter pipes. 2.1.2 Number of Passes (Transducer Mounting) The user is prompted to enter the number of times the sound path crosses the pipe. Allowed values are 1 to 16. -
Page 9: Pipe Wall Thickness
2.1.5 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. 2.1.6 Pipe Roughness The user is prompted to enter a value for the peak/trough height of the roughness on the inside surface of the pipe. -

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. -

Below the scope trace is a progress bar which shows the progress of data and parameter value download. 2.3 Display of Measurements This section, see figure (6) below, displays; • Flow velocity (m/s) • Flow rate (l/min) • Mass flow rate (kg/min) •... -
Page 12: Signal Based Diagnostics
To just make diagnostic measurements press the Read Meter Settings button. 2.4.1 Signal Based Diagnostics This section displays diagnostics related to the signal strength and SNR of the received sonic signal; • Gain • Signal • Noise • SNR 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 decibels (dB). -
Page 13: Time Based Diagnostics
2.4.2 Time Based Diagnostics This section shows diagnostics relating to the timing measurements being made by the UFM. • Delta Time • Transit Time Up • Transit Time Down • dT Offset 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. -

entered by the user during Quick Start. 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 ± 5 mm to achieve a figure of 100 %. If more movement is necessary, then one of the pipe parameters is probably incorrect. -
