Industrial compressed air flow measurement
Fields of application
Flowmeters withstand industrial environments and vibrations.
These flowmeters for compressed air are ideal for companies operating in industrial environments: pharmaceutical, glass, automotive, chemical, metallurgy, food and beverage.
Benefits
The FWD is an ultrasonic flowmeter that measures air flow in pipes from 25 mm to 200 mm. This air flow meter is ideal for managing compressor operating load, controlling the amount of air used in the plant, and detecting any air leaks in the plant.
