Specifications

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