The working principle and characteristics of turbine flowmeter

? ? ? ? Working principle: Within a certain flow range, the speed of the turbine is proportional to the flow rate of the fluid.

? ? ? ? ?The fluid flow drives the turbine to rotate, and the rotation speed of the turbine is converted into electrical pulses. The data is displayed by the secondary meter to reflect the fluid flow rate.

? ? ? ? ?Working characteristics of turbine flowmeter: ①Strong anti-impurity ability;

? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?②Strong anti-electromagnetic interference and anti-vibration ability;

? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?③ Its structure and principle are simple and easy to maintain;

? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?④Almost no pressure loss, saving power consumption.

The working principle of the turbine flowmeter: fluid flows through the sensor, because the blades of the impeller have a certain angle with the flow direction

? ? ?The impulse of the fluid makes the blade have a rotational moment, and the blade rotates after overcoming the friction moment and fluid resistance.

? ? ?Under certain conditions, the rotation speed is proportional to the flow velocity. Due to the magnetic permeability of the blade, it is in the magnetic field of the signal detector.

? ? The rotating blade cuts the lines of magnetic force, so that electrical pulse signals are induced at both ends of the coil.

? ? ? ?This signal is amplified and shaped by the amplifier to form a rectangular pulse wave with a certain amplitude, which can be transmitted to the display instrument.

? ? ? The instantaneous flow rate and cumulative amount of fluid are displayed.

? ? ? In a certain flow range, the pulse frequency f is proportional to the instantaneous flow Q of the fluid flowing through the sensor.
