Working Principle: The flow of liquid past the wheel causes the wheel to rotate at a rate which is proportional to the velocity of the fluid. A voltage pulse is induced in the coil as each blade on the turbine wheel moves past it and these pulses are measured by a pulse counter.

Application Area: 1) Can be used at high temperature and pressure 2) Suitable for low viscosity high flow measurements 3) Used in petrochemical industries, in Aerospace applications etc.
