A gas pressure gauge is an industrial instrument that uses an elastic element as its sensing element to measure and indicate the pressure of a gas system. It is a mandatory verification measuring instrument used for trade settlement. Product types include vacuum pressure gauges and explosion-proof types.
With the trend towards intelligentization, digital pressure sensors are being integrated into smart gas meters to achieve safety protection functions such as pressure monitoring, leak warning, and automatic valve shut-off. Related technological developments include structural improvements to dedicated pressure gauges used for gas meter leak detection.
