Adopting the patented mechanical temperature compensation component technology of Zhenlan (patent number: ZL 2013 2 0041589.0), the measurement reading is corrected by changing the rotational volume of the gas meter when the temperature changes;

Adopting the patented gas meter redundancy control technology of Zhenlan (patent number: ZL 2015 1 0718165.7), it effectively avoids the gas meter from becoming slower and slower over long-term use, and can effectively reduce the transmission difference;

The non-destructive sealing process for gas meters with invention patents (patent number: ZL 2013 1 0029190.5) ensures long-term sealing and corrosion resistance of gas meters;

High operational sensitivity, with a starting flow rate of up to 1dm ³/h;

● Low pressure loss, less than 160Pa at a flow rate of 6m ³/h;

Good sealing performance, safer to use. The protective shell is coated with imported sealant and rolled with a seamless stainless steel sealing ring, allowing the gas meter to withstand a high-pressure sealing test of 75kPa;

The working temperature range is wide and can be used normally in an environment of -25 ℃ to+55 ℃;

A gas meter that can withstand a 1000h salt spray test can be configured.
