SFM Flow Meter, 4 - 24 gpm
The SENTRY I FLOW METER was developed to provide accurate flow rates of pumps from 0 - 100 PSI, at flow rates anywhere from 4 - 24 gpm. By adjusting the handy ball-valve, the SENTRY I FLOW METER can tell you the condition of the pressure tank, pressure switch, pump and if there are any restrictions in the water line.
