BES - EXPERTS IN FLOW METER TECHNOLOGY
Ultrasonic Flow Meter
An ultrasonic flow meter measures liquid flow using sound waves rather than physical contact with the fluid — making it one of the few non-invasive flow measurement technologies available. BES Flowmeters supplies ultrasonic, digital, gas and variable area flow meters for Australian industrial and process applications where non-invasive measurement, retrofit installation, or specialised gas/liquid handling is required.
How Ultrasonic Flow Meters Work
Ultrasonic meters send sound waves through (or around, for clamp-on types) the liquid and measure the time difference between upstream and downstream signals to calculate flow velocity. Because there’s no contact with the fluid, they’re ideal for retrofit installations, corrosive liquids, or applications where you can’t cut into the pipe.
Flow Meter Technology Range
Beyond ultrasonic, BES Flowmeters supplies a full range of technology-specific flow meters:
- Digital flow meters — electronic readout and data logging for modern process control
- Gas flow meters — purpose-built for gas measurement applications
- Variable area flow meters and rotameters — visual, mechanical flow indication for simple monitoring needs
- Flow transmitters — signal conversion and transmission for integration with control systems
Choosing the Right Flow Meter Technology
Ultrasonic meters send sound waves through (or around, for clamp-on types) the liquid and measure the time difference between upstream and downstream signals to calculate flow velocity. Because there’s no contact with the fluid, they’re ideal for retrofit installations, corrosive liquids, or applications where you can’t cut into the pipe.

Frequently Asked Questions
Ultrasonic flow meters measure flow without contacting the liquid, making them ideal for retrofit installations, corrosive fluids, and applications where cutting into the pipe isn’t practical.
Standard liquid ultrasonic meters aren’t suited to gas — for gas applications, use a dedicated gas flow meter designed for gas density and compressibility characteristics.
They’re the same technology — “rotameter” is the common trade name for a variable area flow meter, which uses a float that rises and falls with flow rate in a tapered tube.
A flow transmitter converts the flow signal from a sensor into a standard output (such as 4-20mA) for integration with control systems, PLCs or SCADA.
