Features

The FWD-N is an ultrasonic flowmeter that measures nitrogen gas flow in pipes from 25 mm to 80 mm. Nitrogen gas flowmeters are essential for ensuring the smooth running of industrial processes, optimizing their efficiency, detecting possible nitrogen leaks, and preventing waste while guaranteeing safety.
