BoilerTrak 620S-BT Insertion Thermal Mass Flow Meter by Sierra Instruments

BoilerTrak 620BT Thermal Mass Flow Meter from Sierra Instruments

Insertion Thermal Mass Flow Meter for Boiler & Heater Efficiency

The BoilerTrak™ 620S-BT by Sierra Instruments has been designed to provide an economical, easy-to-install solution for precise natural gas measurement for heaters and boilers to increase efficiency. This instrument is also suited for compliance with new regulations for burning natural gas and propane in commercial boiler applications.

Developed as a fuel measurement solution for customers facing compliance to the California Global Warming Solutions Act of 2006, the BoilerTrak™ meets all of the requirements for a stationary combustion fuel meter. This product is optimized for highly accurate and repeatable mass flow metering as mandated by the EPA, including:

  • Methane (CH4)
  • N20
  • SF6
  • HFCs
  • PFCs
  • CO2
