BoilerTrak 620S BT Mass Flow Meter

Sierra Instruments’ Boiler-TrakTM Immersible Thermal Mass Flow Meter provides an optimized solution for natural gas or propane flow measurement applications.

Boiler-Trak is designed to provide an economical solution to new regulations for the burning of natural gas or propane in heaters and boilers. The meter's sensor offers long-term reliability and a 200 millisecond response to changes in flow rate.

The versatile microprocessor-based transmitter integrates the functions of flow-range adjustment, meter validation and diagnostics in a probe-mounted NEMA 4X (IP65) housing. Mass flow rate and totalized flow, as well as other configuration variables, are displayed on the meter's 2 x12backlitLCDpanel.

The meter also provides an optical/galvanic isolated 4-20 mA output and two alarm outputs along with a programmable pulse output for remote totalization. An optional Modbus Communications package is also available. The programmable transmitter is easily configured via RS-232 and Sierra’s Smart InterfaceTM WindowsTM based software (supplied with the meter) or three push buttons in the device. Boiler-Trak is suitable for pipes or ducts from 1-inch to 6-inches.
