Blue White Industries; Horizontal Flow Pipe Flowmeter; Color: Clear; Size: 4"; Pressure Rating: 75 psi
Blue White F‑300 Series 4" PVC Flowmeter, 75‑420 GPM, F‑30400P, is a commercial‑grade acrylic pitot‑tube flow meter designed to mount on 4" Schedule 40 PVC (or copper) piping and measure water flow from about 75 to 420 GPM in closed‑pipe pool and spa systems.
What It Is
The F‑30400P is part of Blue‑White’s F‑300 series variable‑area (pitot‑tube) flow meters, built specifically for pool and spa recirculation lines. It saddles onto a 4" PVC or copper line and uses an internal pitot tube to sense flow; a float and scale in the clear acrylic body provide an easy‑to‑read, direct GPM/LPM indication.
This model is commonly used on commercial pools, aquatic centers, waterparks, and large institutional pools to monitor filtration and recirculation flow. It is typically installed after the filter and heater on the main return line so operators can confirm turnover rates and verify that valves or dirty filters are not restricting flow.
