Description

Turbine flowmeter

Technical Field

The invention relates to the technical field of flowmeters, in particular to a turbine flowmeter.

Background

The turbine flowmeter is characterized in that an impeller is impacted when fluid passes through a pipeline, the impeller overcomes friction torque and fluid resistance torque to rotate, a blade periodically cuts magnetic lines of force generated by an electromagnet in a certain flow range, the magnetic flux of a coil is changed, a pulsating potential signal, namely an electric pulse signal, is induced in the coil according to the electromagnetic induction principle, and the frequency of the electric pulse signal is in direct proportion to the flow of the measured fluid. And the device is used for calculating the fluid flow by measuring the rotation angular speed of the impeller. Most of existing turbine flow meters in the market are applied to measurement of various fluid media, but not all media have lubricity, and after the measurement of the media without lubricity is completed, the measured media are easily adsorbed on the inner wall of a pipeline and then are condensed to dry, so that the turbine flow meters are damaged, and the measurement accuracy is affected.
