What is a rotary gas meter?
Elster Rotary gas meters are characterized by compact dimensions and extended measuring range. They ensure high accuracy, even under low or irregular gas flow conditions.
The rotary meters combine tried and tested product features of the RPM and IRM rotary meter product lines with new advanced features. The new rotary meter offers a set of features that meets virtually all market applications in one simple design.
How does it work?
The rotary gas meters utilize 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 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.
What problems does it solve?
Greater rangeability than other meters
Significant reduction in device inventory
Increased maximum operational pressure (MAOP)
Low pressure drop, enabling flexibility in station design
Reduction in hazardous noise for safer operations
Reduction in piston speed for longer asset life
Low total cost of ownership
Simple installation and commissioning
Compact design and ease of use
Environmentally friendly design
Bundled with electronic volume corrector for single vendor sourcing.
