Description:

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;

Features:

Wide range, 0.016~6m³/h
Measuring accuracy 1.0 grade
Starting flow <1dm³/h
Low pressure loss
Multiple gas quality switching
Wide range error accuracy adjustment mechanism
Valve system redundant control technology
Not affected by impurities in the medium
