Flow Meter

FMG80A-Series 1/4″ to 3/4″ Pipe/Tube, Low Flow Electromagnetic Flow Meter

The FMG80A Series flow meter is designed for low-flow chemical injection or difficult-to-meter applications with pulsating metering pumps in ¼ to ¾” pipe/tube. The housing is made of sturdy splashproof HDPE plastic.

With no moving parts, the FMG80A Series can handle fluids containing particulate matter without clogging or jamming, keeping maintenance at a minimum. With no metallic parts (100% PVDF body and PVDF carbon fiber-filled electrodes), the meter is corrosion-resistant and compatible with a wide range of chemicals. Accuracy is maintained with conductive fluids (>20 micro Siemens) of varying viscosities and densities.
