The gold standard for low flow measurement
The rotary piston gas meters GM16 meet the highest demands on the reliable and precise reference measurement of low flow up to 0.01 m³/h. You achieve an excellent measuring accuracy of 0.5% MW + 0.005% EW. Both variants – with 1 or 2 HF pulse generators – are suitable for operation up to 6 bar overpressure. The new generation of reference gas meters is not only suitable for air, but also for hydrogen, natural gas and other non-flammable and non-aggressive gases. With the continuous, absolutely pulsation-free and highly precise flow measurement, the reference gas meters from Ehrler Prüftechnik are the gold standard in the field of low flow measurement – also for hydrogen.
Measuring principle
The reference gas meters GM16 operate according to the direct displacement principle (RPD -rotary positive displacement), in which two counter-rotating pistons convey a fixed volume from the inlet to the outlet of the gas meter with each full revolution. Due to the specially shaped pistons, an absolutely pulsation-free continuous operation can be realized (patent pending).
