Description 4-20mA Thread Flange High Precision Turbine Flowmeter Liquid Turbine Flowmeter
Turbine flowmeter (hereinafter referred to as TUF) is the main variety of impeller type flow meter, impeller type flowmeter, anemometer, water meter, etc.The TUF consists of a sensor and a conversion display instrument. The sensor USES a multi-blade rotor to feel the average flow velocity of the fluid, thereby deriving the flow or total volume.The rotor speed (or number of turns) can be detected by mechanical, magnetic induction, photoelectric method and recorded by the readout device
