Flow Meters : Turbine Flow Meter

A flowmeter is an instrumentation device used to measure and record the flow rate of a gas or fluid. In a turbine flowmeter the fluid flow imparts a force on a rotating blade row, called the turbine. As the turbine rotates it reaches a steady rotational velocity. The rotational velocity of the turbine is proportional to the flow rate of the fluid which can be easily computed by the flow meter.
