First of all, let's talk about how a Turbine Flow Meter works.

A Turbine Flow Meter is inserted in a pipe directly in the flow path.

The mechanical part of the Turbine Flow Meter has a turbine rotor placed in the path of a flowing stream.

The only moving part of the Turbine Meter is the mechanical rotor. The rotational speed of the rotor depends upon the flow velocity. The rotor blades are usually made of stainless steel.

As the rotor spins, the passage of each rotor blade past a pickup point will generate an electrical pulse.

The electrical pulses are created in different ways depending upon the rotor blades themselves and the pickup unit characteristics.
