The diaphragm temperature compensation gas meter is a common diaphragm gas meter with a temperature compensation mechanism. When the temperature of the gas flowing through the movement changes, the synthetic bimetallic strip with different thermal expansion coefficients on the compensation mechanism is triggered to produce flexural deformation, thereby adjusting the diaphragm stroke and changing the rotation volume, thereby offsetting the volume difference caused by thermal expansion and contraction of the gas and achieving fair measurement. The temperature compensation function enables the diaphragm gas meter to have a wider range of environmental adaptability and improve measurement accuracy.

The wide-range diaphragm gas meter can achieve accurate measurement within the flow range of 0.016 to 6 m³/h, covering the ranges of three general gas meters: G1.6, G2.5, and G4. The range ratio reaches 375:1, and the measurement accuracy reaches 1.0 level. The wide-range error accuracy adjustment mechanism is adopted to achieve wide-range and high-precision measurement of the gas meter. The measurement accuracy can also be guaranteed when the output difference changes and the gas quality switches, without the need to replace the corresponding meters with different ranges like ordinary gas meters;

NB-IOT Internet of Things diaphragm gas meter (GPRS optional) is a smart gas metering product that uses GPRS/NB-IoT Internet of Things wireless communication technology to realize user gas data transmission based on diaphragm gas meter. It not only has the accurate metering function of diaphragm gas meter, but also realizes the functions of regular reporting of gas consumption data (automatic meter reading), wireless remote recharge, remote price adjustment, automatic fault reporting, gas consumption record, etc. It is safe, reliable, convenient and practical.
