Inert Gas Flow Measurement

Mass Flow Meters

Sierra's Accu-Flo and Accu-Mass flow meters are designed for measuring air flow and other inert gases. Low pressure drop, millisecond time response and exceptional low-velocity sensitivity make them the ideal instrument for a wide range of research, HVAC and OEM applications.

620S Smart Fast-Flo

Smart Low-Cost Insertion Mass Flow Meter

The Model 620S Fast-Flo® insertion mass flow meter was designed to give customers a highly reliable 200 msec fast time-response (Fast-Flo® Sensor Technology) mass flow meter for light-industrial applications where a NEMA 4X (IP65) enclosure is acceptable. The Model 620S has an accuracy is ± 1% of full scale, 0.2% of full scale repeatability, and the flow range goes up to 20,000 sfpm.

730 Accu-Mass™ Inline Mass Flow Meter

A solution for applications requiring fast-response measurement and low-flow sensitivity. Product accuracy is ± 1% of full scale + 0.5% of reading and the flow ranges from 0-200 scfm to 0-84 sfpm (air) with standard accuracy.
