Fast-Response Insertion Thermal Mass Air Flow Sensor

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 mass 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 How does a thermal mass flow meter for industrial applications work? An insertion thermal mass air flow sensor provides precision measurement of total mass flow rate of gases flowing through closed conduits such as pipes and ducts. Thermal dispersion technology for direct mass flow measurement features: no pressure or temperature compensation needed, no moving parts, low pressure drop, and high turndown.
