Overview

The FastFlo™ 620S is an insertion thermal mass air flow sensor 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

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. Watch the video...
