RS PRO 780 Series Flow Meter 0.25L/min to 6.5L/min

Before installing flow sensors there are a few things to consider which are bends, valves, flow regulators, tee junctions and other fittings with cause the flow to travel faster at one side of the pipe relative to the other. This asymmetry in the flow can affect the calibration and the disturbance should be as far removed from the sensor as possible and ideally put after the flow sensor. Turbine transducers are affected by viscosity and where possible the viscosity (temperature) of the liquid should be kept fairly constant.

Sensor options include:

257-149 - Grey liquid flow sensor,0.25 to 6.5 l/min, 500Hz, 4600 pulses/litre

257-133 - Beige liquid flow sensor,1.5 to 30 l/min, 600Hz, 1200 pulses/litre

These RS PRO flow transducers have been manufactured to the highest standards and with correct installation and maintenance they will last a long time with reliable operation throughout.

A jet of liquid is directed at a free running turbine in a specially shaped chamber. The rate of rotation of the turbine is directly proportional to flow rate and the number of revolutions is proportional to the total amount of liquid passed. The passage of each turbine blade cuts a powerful beam of infra red light, this blocking is detected electronically.
