The wafer type housing of QA and QAe (with electronic totalizer) is made of aluminium. Depending on the version, the volume is displayed on a mechanical (QA) or an electronic totalizer (QAe). QA and QAe Quantometers combine the high accuracy of the Q series of Quantometers with low weight.
The Quantometers are available in a number of flow ranges, diameters and pressure ratings. Depending on the version, a low or medium-frequency pulser and an optical readout or an optical readout with additional M-bus output is available. All of the Quantometers are DVGW approved.
For special industrial applications, stainless steel versions are also available.
