Blue-White F-462 Ultrapure Polysulfone Flowmeter
The Blue-White F-462 is a variable area flowmeter for 2″ lines, reading from 8 to 300 L/min. Its moulded polysulfone body and adapters and its PTFE float mean the liquid touches no metal on its way through.
That suits deionised and other ultrapure water, where metal parts would contaminate the water, and corrosive liquids that would attack a metal float or guide. The scale is printed on the body in both L/min and US gallons per minute, and the meter needs no power or wiring.
Three Flow Ranges
- F-462200: 8 – 80 L/min (2 – 20 GPM)
- F-462500: 20 – 200 L/min (5 – 50 GPM)
- F-462800: 30 – 300 L/min (8 – 80 GPM)
Rib-Guided PTFE Float, No Metal Inside
Instead of a metal guide rod, the PTFE float is kept centred by ribs moulded into the polysulfone body. Only polysulfone, PTFE and the O-rings are in contact with the liquid.

Ideal for Ultrapure Water & Corrosive Liquids
The F-462 is used on larger deionised and ultrapure water lines, and on corrosive liquids, wherever an all-plastic meter is wanted. Fitted in a vertical 2″ pipe run indoors, it gives a direct visual check of flow, and an optional polycarbonate splash shield fits around the meter body.
