Product details

Performance characteristics

Adopting a wide range error accuracy adjustment mechanism to achieve wide range and high-precision measurement of gas meters;

The patented valve system redundancy control technology (patent number: ZL 2015 1 0718165.7) achieves long-term accurate measurement of gas meters;

The patented non-destructive rolling edge sealing process (patent number: ZL 2013 1 0029190.5) ensures long-term sealing and corrosion resistance of the gas meter;

Wide range of measurement, achieving accurate measurement of flow rate range of (0.016~6) m ³/h, with a range ratio of up to 375 times;

High operational sensitivity, with an initial flow rate of less than 1dm ³/h;

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

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