Ultrasonic Gas Meter module is a module that uses ultrasonic to achieve gas measurement. The module has no mechanical transmission components in design, low noise, excellent anti-blocking performance, strong anti-interference ability, no wear, long life-time and low overall use cost. The measurement part adopts time difference method that is the most mature method at present. The accuracy of time measurement is guaranteed by the timer chip (GP31) produced by AMS Company.
