Products Description

The LWGY series flange type liquid turbine flowmeter is the main type of velocity type flowmeter. When the measured fluid flows through the turbine flowmeter sensor, the impeller is forced to rotate under the action of the fluid, and its speed is proportional to the average flow rate of the pipeline. At the same time, the blade periodically cuts the magnetic field lines generated by the electromagnet, changing the magnetic flux of the coil. According to the principle of electromagnetic induction, a pulsating electric potential signal will be induced inside the coil, The frequency of the electrical pulse signal is proportional to the flow rate of the measured fluid.
