Zenner Two-Pipe Diaphragm Gas Meter is suitable for various gas media. The integrated calibration system coordinates the movement of the valves in relation to the optimum gas flow. The excellent linearity of the error curve is guaranteed even at low flow rates. Due to the valves’ optimum rotating characteristics, the Qmin value remains stable and the gas meter is resistant to contamination.
