Sierra Instruments’ FastFlo™ 620S Immersible Thermal Mass Flow Meter
Sierra Instruments’ FastFlo™ 620S Immersible Thermal Mass Flow Meter provides an economical solution for gas flow measurement applications. The meter’s sensor offers long-term reliability and 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, can be displayed on the meter’s optional 2 x 12 backlit LCD panel.
The meter also provides an optical/galvanic isolated 4-20 mA output and two alarm outputs. The programmable transmitter is easily configured via RS-232 and Sierra’s Smart Interface™ Windows™ based software or three push buttons in the device. Modbus RTU is also supported. The 620S is suitable for pipes or ducts from 1-inches to 48-inches (DN50 to DN1200).
