                                           QTLD-LWGY Liquid Turbine Flow Meter
 LWGY intelligent liquid turbine flowmeter (turbine flow sensor and display instrument supporting turbine flowmeter).
The sensor has the characteristics of high precision, good repeatability, long life and simple operation.
It can be widely used in petroleum, chemical, metallurgy, paper and other industries to measure the volume instantaneous flow and volume total of liquid

The working principle of the turbine flowmeter is as below:
Fluid flows through the sensor shell. Since the blade of the impeller has a certain Angle with the flow direction, the momentum of the fluid makes the blade have a rotational torque. 
After overcoming the friction torque and fluid resistance, the blade rotates.The speed is stable after the torque balance, under certain conditions, the speed is proportional to the flow rate, 
because the blade has magnetic conductivity, it is in the magnetic field of the signal detector (composed of permanent magnetic steel and coil),
The rotating blade cuts the magnetic field line and periodically changes the magnetic flux of the coil, thereby inducing electrical pulse signals from both ends of the coil. 
This signal is amplified and shaped by the amplifier to form continuous rectangular pulse waves with a certain amplitude.
It can be transmitted to the display instrument to show the instantaneous flow or total amount of fluid.
