Honeywell Elster has combined tried and tested product features of their RPM and IRM rotary meter product lines with new developments into a single product. The new Honeywell Elster Rotary Gas Meter offers a feature set that meets virtually all market applications in one simple design. Rotary all-by-one, RABO!
The Elster Rotary Gas meter utilizes the rotary-type positive displacement principle of operation which makes volumetric measurements by displacing finite volumes of gas. The positive displacement occurs within a cavity formed between the meter’s internal housing and its rotating impellers. The counter-rotating “figure-eight” impellers turn as a result of pressure drop across the meter’s inlet and outlet created as downstream gas is consumed. The rotating impellers separate the flowing gas into small, finite, volumes and are counted using a mechanical index.
