Insertion Mass Flow Meter - BoilerTrak™ 620S BT

Thermal Mass Flow Meter Increases Boiler & Heater Efficiency

BoilerTrak™ is designed to provide an economical and easy to install solution for precise natural gas measurement to heaters and boilers to increase efficiency. The instrument also suited for compliance to new regulations for burning natural gas in commercial boiler applications.

The versatile microprocessor-based transmitter integrates the functions of flow-range adjustment, meter validation and diagnostics in a well-packaged 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 x 12 backlit LCD display panel.

BoilerTrak™ also provides an optical/galvanic isolated 4-20 mA output, two alarm outputs, and one contact input for range or gas selection. The programmable transmitter is easily configured via RS-232, Sierra’s Smart Interface™ software, or with three push-buttons located on the instrument.

Operating Principle

Sierra’s unique BoilerTrak 620S BT sensor probe is responsible for the unsurpassed accuracy and reliability of Sierra mass flow meters. The sensor consists of two sensing elements–a velocity sensor and a temperature sensor which automatically corrects for changes in gas temperature. When power is applied to the flow meter, the transducer electronics heats the velocity sensor to a constant temperature differential above the gas temperature and measures the cooling effect of the gas flow. The electrical power required to maintain a constant temperature differential is directly proportional to the gas mass flow rate. The meter electronics measure this power and convert it into a linear 0-5 VDC (0-10 VDC optional) and 4-20 mA output signal

The BoilerTrak sensors are reference-grade platinum resistance temperature detectors (RTD) encapsulated in glass. The platinum RTD wire is wound on a rugged ceramic mandrel for strength and stability. The sensor is located at the tip of a 0.375 inch (3/8”) diameter, 304 stainless steel probe which is inserted in the gas stream. The Boiler-Trak electronics are packaged in a weather-proof NEMA 4X (IP65) enclosure mounted either directly on the sensing probe or remotely up to 100 feet (60 meters) away.
