Rotary Gas Meters

Rotary gas meters, such as the ROOTS Solid State Pulser, allow for the measurement of large amounts of gas flow. Rotary gas meters have multiple applications and can be used in both indoor and outdoor locations.


  • Bounceless Switch
  • Internal Mounting
  • No Moving Parts

Diaphragm Gas Meters

Diaphragm gas meters, such as the Elster AC250, allow for the measurement of flow channels designed for low pressure losses. The volume is displayed directly on the meter itself. Diaphragm gas meters allow building operators to measure very small amounts of gas accurately.

Insertion Mass Flow Meters

Insertion mass flow gas meters, such as the BoilerTrak 620S, are inserted directly into the flow stream to measure the flow rate of gases, liquids, or slurries in stacks, irregularly shaped lines, and process ducts. Insertion mass flow gas meters are ideal for testing and verification purposes, non-revenue check metering, and more.
