Smart Gas Meter

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;

The camera direct-reading IoT diaphragm gas meter is based on a mechanical diaphragm gas meter and is equipped with a micro camera module, LED flash and wireless communication module (GPRS/NB-IOT/LORA). It uses the camera to capture the data of the character wheel, uploads it to the platform and intelligently recognizes the image to obtain gas consumption information. It is an intelligent gas metering product that realizes wireless collection, measurement and billing of user gas consumption data, and conveniently and effectively realizes the digitization and visualization of the gas meter.

IC card prepaid diaphragm gas meter, based on the valve diaphragm gas meter, integrates contactless radio frequency card technology and combines with the Internet of Things wireless communication module. The gas purchase volume is written into the IC card. After the user swipes the information in the IC card into the gas meter, the gas meter will automatically open the valve to supply gas. During the user's use, the microcomputer in the gas meter automatically deducts the remaining volume. When the purchased gas volume is used up, the gas meter will automatically close the valve to cut off the gas.

The wireless remote transmission transformation module of the gas meter is used to transform ordinary gas meters to realize wireless communication functions, such as remote meter reading, remote price adjustment, and tiered gas price. Based on the modular design concept, the control part of the communication module is completely independent and can be freely plugged and assembled. As long as the valve and pulse sampling are reserved in advance on the base meter, the wireless communication function can be realized by installing the communication module. It is an ideal and economical gas meter intelligent upgrade and transformation solution, which can realize automatic meter reading, remote recharge, remote valve control, remote price adjustment, automatic fault reporting, gas leakage alarm and other IoT meter functions.
