The Fuji Electric FWD Ultrasonic Flow Meter measures flow rates of the air or nitrogen gas in pipes from 25mm to 200mm. As an air flow meter it is ideal for management of the operating load rate of the compressor, management of the amount of the used air in the factory and detecting of the air leakage in the factory.

With no moving parts the FWD has high resistance to fluids containing oil, vapor and dust. The wide rangeability of 1:60 allows for accurate measurements of even smaller flow rates. The built in battery (10 year life span) makes power line construction unnecessary. An external power supply of 24VDC is also available. Flow ranges cover from ±0.6-±35 m³/h up to ±240-±11870 m³/h depending on pipe size. Various output functions are available. Cable lengths of 5m or 20m can be selected.
