Elster-Instromet quantometers QA and QAe are flow meters that display the flow volume in actual cubic metres. Depending on the version, the volume is displayed on a mechanical (QA) or an electronic index (QAe). Quantometers QA and QAe, for measuring gaseous media, combine the high accuracy of the Q series of quantometers with low weight as a result of their aluminium housing.
The quantometers are available in a number of flow ranges, nominal diameters and pressure ratings. Depending on the version, a low- or medium-frequency pulse generator and an optical readout or an optical readout with additional M-bus output is fitted. All of the quantometers in the QA/QAe series are DVGW and PED tested and approved.
For industrial applications, stainless steel versions are also available.
