Smart Thermal Gas Meter

●Gas flow metering in standard condition ensure high precise, no temperature or pressure compensation

●Automatic gas identification technology to meet metering requirements of various of gas specified in 12T / 10T 

●Without movement parts or mechanical wear, ensures long-term metering stability, thus minishes the data difference between supply and consumption

●Strong anti-interference capacity (No magnetic component)

●Small flow leakage protection guarantees the safe usage

●Convenient installation as with compact design and small size

●Independent measurement unit, high-level data security protection and tracking mechanism 

●Seven key technologies and six patents

●Multiple communication modes(GPRS / NB-IoT / LoRaWAN / WM-bus) support remote communication and valve operation 

●Lithium battery with 5 years life

Principle

Microelectronic thermal sensor applied as the gas flow detection element of the smart thermal gas meter. As shown in the figure, the sensor includes a micro-heater and a pair of symmetrical temperature sensors. When there is no gas flow, the two sensors are at the same temperature field, while there is any flow passby, the change of the temperature will be detected by the sensors. The temperature field has a corresponding relationship with the gas flow.
