LWGY Series Turbine Flow Meter
|
|
Liquid Turbine Flow Meter
|
Description
Turbine Flow Meter is a main type of impeller flow meter
including the Anemoscope and Water meter. It is made up of
Sensor and Conversion-Show. The Sensor reacts to the
average velocity of fluid with multi-blades rotor so as to
speculating the flow value and the accumulative flow value.
