Water Flow Meters & Rotameters
A flow meter tells you exactly how much water is moving through a line — essential for setting RO recovery, dosing chemical feed, or verifying a system's output. We carry panel-mount and inline flow meters and rotameters from Blue-White, PureT and Mazzei in the common residential and light-commercial GPM ranges.
How to choose a flow meter
Pick your GPM range. Meters read best in the middle of their range — match the meter's span (like 0.5–5 GPM) to your actual flow.
Inline vs. panel mount. Inline rotameters thread into the pipe; panel-mount meters read at a glance on an equipment board.
Mind the connection. Confirm port size and thread (MNPT/FNPT) before ordering.
Gas or liquid. Some meters (like ozone gas kits) are calibrated for gas — use a liquid meter for water.
Tell us the flow range and connection and we'll match a meter. Ask us.
