Model 620S Series Fast-Flo® NEMA 4X (IP65) 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.  

The Model 620S is commonly used to measure air, nitrogen or any other inert gas. In addition, the compact and versatile microprocessor-based transmitter integrates the functions of flow-range adjustment, and meter validation and diagnostics. 

The Model 620S enclosure is available in probe-mount or remote-mount configurations and has a 316 stainless steel, 3/8-inch diameter insertion probe available in lengths from 3.7-inches up to 24-inches. Mass flow rate and totalized flow, as well as other configuration variables, can be displayed on the meter's optional 2 x 12 backlit LCD readout.
