Ultrasonic flow metering from Gentech The latest innovation from switching, sensing and control solutions specialists Gentech International is the "no moving part" FMS-01 ultrasonic flow meter, specially developed for low cost applications such as beverage delivery, heating systems, chemical dosing and water purification.

The Gentech FMS-01 uses ultrasonic emissions to measure volume and flow rate and has no moving parts, so it will not clog or jam.

The sensor is also unaffected by contaminated fluids, guaranteeing a longer life.

Ultrasonic technology ensures performance over a wide range of fluids with automatic viscosity compensation and has an operating temperature range of -10C to +85C.

Featuring push fit connection via 3/8" BSP as standard, the flow metering range is 1-20 litres per minute, with accuracy +/- 3% and linearity of +/- 1% over the range.

With a response time of better than 0.4 seconds, and a pulse output of 0-5 volt pulses of 2 mS duration and 752 pulses per litre, the device has a low pressure drop of 0.4 bar at 20L/min.
