Ultrasonic Gas Meter Module

USM Module Series
Ultrasonic Gas Meter Module G2.5M-G4M uses a pair of ultrasonic gas transducers that installed oppositely at upstream and downstream, based on TOF (Time of Speed) principle to measure flow velocity of gas medium, with built-in temperature and smart software algorithm, consumed gas volume can be calculated and displayed on meter’s screen.
PCI patented L shape gas flow channel, the effective distance between two transducers are longer, which facilitates the measurement accuracy, it's also anti-contamination that guarantees long-term stability of accuracy.
Segment: Gas Flowmeter
Division: Ultrasonic Gas Meter
