Flow Verification Sensor (FVS)

MICRO-FLO, Flow Verification Sensor (FVS)

Max Feed: .03 – 7.0 LPH

Max Pressure: 150 PSI (10 bar)


√  Designed to monitor pump output.

√  The pump’s electronics will continuously monitor the Micro-Flo FVS to ensure chemical injection.

√  Clear lens; visual indication of chemical injecting.

√  Designed for Diaphragm and Peristaltic Pumps.
