FastFlo 620S Insertion Thermal Mass Air Flow Sensor

Sierra Instruments FastFlo 620S Mass Flow Meter available at Procon Instrument Technology AustraliaFast Response Insertion Thermal Mass Air Flow Sensor

Sierra Instruments FastFlo™ 620S is an insertion thermal mass air flow sensor that has been designed to give you a highly reliable, responsive and affordable mass flow measurement for light industrial applications where a NEMA 4X (IP65) enclosure is acceptable. This airflow sensor:

  • Includes a compact, versatile, microprocessor-based transmitter
  • Integrates flow-range adjustments, and meter validation and diagnostics
  • Gives you the ability to “field-validate” your meters calibration
  • Increases efficiency with fast response time within 200 milliseconds
  • Wide Flow ranges from 0 to 42,000 scfh
  • Easy to install in the field or retrofit
  • Optimised air, nitrogen and inert gas measurement for 1, 2, 3, 4 inch sch
  • 40 pipe sizes

Operating Principal: Thermal dispersion technology for direct mass flow measurement featuring no pressure or temperature compensation needed, no moving parts, low pressure drop, high turndown.
