Liquid Turbine Flow Meter

Fluid flows through the meter shell, because the blade of the impeller has a certain angle with the flow direction, the impulse force of the fluid makes the blade have a rotational torque, and after overcoming the friction torque and fluid resistance, the blade rotates, and the rotational speed is stable after the torque is balanced. Under certain conditions, the rotational speed is proportional to the flow velocity. 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, so that both ends of the coil induce an electrical pulse signal, which is amplified and shaped by the amplifier to form a continuous rectangular pulse wave with a certain amplitude, which can be transmitted far to the display instrument to show the instantaneous flow or total amount of fluid. In a certain flow range, the pulse frequency is proportional to the instantaneous flow of the fluid flowing through the meter.

Features：

High precision, generally +1% Ror +0.5% R, even +0.2% R can be customized. (R is for reading error.)

Good repeatability, with a short term repeatability of0.05%~0.2%. Due to its good repeatability, very high accuracycan be achieved after freguent calibration or online calibration. lt is a preferred choice for flow meters in tradesettlement.

Output pulse frequency signal, suitable for total gquantity measurement and connection with computers. Withoutzero drift, and strong anti-interference capability.

The original pulse frequency range (10Hz~1.5KHz) with strong signal resolution.

Suitable for high-pressure measurement, no need to open holes on the meter body. There are many types ofspecialized sensors, which can be designed according to the needs of users, such as low-temperature, bidirectional, downhole, and sand mixingtypes.
