Product Description

1.Functions
Turbine flowmeter (hereinafter referred to as TUF) is a kind of impeller type flow meter, which also includes anemometer and water meter, etc. TUF is composed of sensor and converter. The sensor uses a multi-blade rotor to feel the average velocity of uid, thus to derive the ow rate or totalizer. Today, TUF has been widely used in various sectors like petroleum, chemical, scientic research, national defense and metering.
HLWGY series Turbine Flowmeter has simple structure, high accuracy, good repetitiveness, fast response and convenient maintenance. It is widely used for liquid without corrosion to stainless steel, Al2O3 or hard alloy, without bre or particle and kinematic viscosity less than 50×10-6m2/s.
Working Principle
Figure 1 shows the structure diagram of turbine ow sensor. Seen from the gure, when the measured uid ows through the sensor, under the action of uid, the impeller stresses and rotates. Its speed is in direct proportion to pipeline average velocity. The rotation of impeller cyclically changes the magnetic resistive value of magnetoelectric converter. The magnetic ux in the detection line diagram consequent cyclically changes, generating periodic indu-ction electric potential, i.e., electric pulse signal. After being amplied by the amplier, it is sent to the display meter for displaying.
