Ultrasonic gas meter is a fully electronic gas meter that uses the principle of time difference method for flow measurement. It has the characteristics of accurate measurement, wide range ratio, wide temperature adaptation range, small size, high reliability, and has the function of temperature and pressure compensation. The product adopts a fully independent research and development program to break the monopoly of foreign technology and realize the independent control of key technologies.

On the basis of the ultrasonic gas meter, the cut-off ultrasonic gas meter adds safety monitoring functions such as leakage alarm linkage, overpressure/loss of pressure monitoring, abnormal temperature monitoring, overcurrent, slight leakage, abnormal gas consumption, etc. The valve in the gas meter is used to replace the external valve. When abnormal conditions occur, the gas meter will quickly cut off the valve. At the same time, the gas meter will report the alarm information to the customer management platform and the user's mobile phone in real time to realize the closed loop of safety management.
