RS PRO Flow Meter, 0.05 → 10 L/min Max

The mini turbine flowmeter is designed to give high performance and competitive pricing. Its totally non-metallic wetted components make this the ideal choice for the metering of aggressive chemicals including ultra-pure water. The standard inlet tubes are barbed to accept 8mm hose sizes. The bearings are made of sapphire for long life and reliability, the body is moulded PVDF as standard and the 'O' ring seal is typically Viton®.

At the heart of the meter is a precision turbine that rotates freely on robust sapphire bearings and contains over-moulded magnets that are detected through the chamber wall by a Hall effect detector. The output is a stream of NPN/PNP pulses that are readily interfaced with a most electronic display or recording devices. This combination of materials and technology ensures a long life product with reliable operation throughout.

The liquid flow rate can be controlled by applying different-size jets (attached):

When used in automotive applications, the formation of vapour should be minimised by fitting the transducer between the fuel pump and the carburettor, but before any pressure regulator. The device should be mounted vertically if vapour is likely to form.
