FastFlow 620S Insertion Thermal Mass Air Flow Sensor

Fast Flo 620S Insertion thermal mass air flow sensor by Sierra InstrumentsFast 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 meter’s 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.
