Liquid turbine flowmeter has these components: turbine, spiral-shaped vane, bearing of turbine, and preamplifier.
A liquid turbine flowmeter is a relatively popular flowmeter, the device has its own characteristics, specifically in the fully intelligent, digital circuit design, simple structure, lightweight, less processing parts, easy maintenance, responsive, large flow capacity and can adapt to high parameters.
Liquid turbine flowmeter in the process of metering, when the measurement medium through the flow meter, impacts turbine blades, through the corresponding structure, in the process of periodic rotation of the impeller blades, the turbine’s rotational angular velocity is proportional to the fluid flow rate.
The meter’s magnetoresistance also undergoes periodic changes, so that the flowmeter and the meter flow rate into a proportional voltage pulse signal, which makes the flow rate and the signal in the role of a low-power amplifier to send the signal to the microcontroller metering system.
It undergoes a series of calculations and corrections, the pulse signal into an analog electrical flow, and then indicates the instantaneous flow value.
The above is the introduction to the working principle and components of the liquid turbine flowmeter, if you have any questions, welcome to contact us.
