1. Ultrasonic Gas Meter use ultrasonic measuring technique, which are featured with wide measuring range, high accuracy.
2. When the ultrasonic gas meter works, due to there being no moving element in channel, few limits of gas' physical property and stable measuring accuracy, so it doesn't exist any changes of accuracy aroused by aging of diaphragm.
3. Ultrasonic Gas Meter could measure the instantaneous flow. It could cut off valve when it have sudden overload flow. And it also has high security.
4. When used, there is no mechanical movement and noise. The volume of complete meter is half of mechanical meter.
