SENSOR TO READ ROTATIONAL SPEED OF AXIAL TURBINE IMPELLER IN FLOW METER

SENSOR TO READ ROTATIONAL SPEED OF AXIAL TURBINE IMPELLER IN FLOW METER

SENSOR TO READ ROTATIONAL SPEED OF AXIAL TURBINE IMPELLER IN FLOW METER

(OP)
Not sure if this is in the right place. I am trying to locate a sensor that will read rotational speed of an axial turbine wheel located in a hydraulic flow meter. I have the capability to design and have the housing made. Pressure and temperature sensors are easy to get. I have taken an existing flow meter apart, the turbine wheel is made from a ferrous metal. The sensor is not isolated from the pressure of the oil flowing through the turbine (250-350 bar) sealing is by way of a copper washer and an o-ring. The sensor I am assuming is a hall effect sensor.

Does anyone out there know where I would get such a sensor?

RE: SENSOR TO READ ROTATIONAL SPEED OF AXIAL TURBINE IMPELLER IN FLOW METER

off the top of my head no I don't. Turbine meters normally work on the basis of pulses, but whether these are based on direct amplified pulses from the rotor or manufactured via some other signal I don't know - you would have to talk to the vendor who made the one you took apart.

See if one part of the rotor is essentially a magnet

Can't understand why you're trying to do this yourself - can't you buy a ready made functioning meter?

If you took a meter apart, did it not have a sensor already attached??

There's a lot here which doesn't seem to make sense

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Look for "proximity sensors" or "magnetic pick-up".
