Turbine Flow Sensor & Meter — real BROIL product photograph
ROTOR VELOCITY — VELOCITY FLOW METER

Turbine Flow Sensor & Meter

The rotor spins with the flow.

Turbine flow meters use the mechanical energy of flowing fluid, causing a rotor to rotate at an angular velocity proportional to the fluid flow rate or velocity within the flow path. Pickup coils capture this angular velocity and generate an electrical signal directly proportional to flow rate.
