- Fast delivery—ships next-day from stock
-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
