Insertion Thermal Mass Flow Meter for Boiler & Heater Efficiency

Sierra Instruments’ BoilerTrak™ Immersible Thermal Mass Flow Meter provides an optimized solution for natural gas or propane flow measurement applications. BoilerTrak 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 probemounted NEMA 4X (IP65) housing. Mass flow rate and totalized flow, as well as other configuration variables, are displayed on the meter’s 2 x 12 backlit LCD panel. 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 Interface™ Windows™ based software (supplied with the meter) or three push buttons in the device. Optimized natural and propane measurement for 1, 2, 3, 4 inch sch. 40 pipe sizes.
