Vortex flowmeter: mainly used for flow measurement of industrial pipeline media fluids, such as gases, liquids, vapors, and other media. Its characteristics are small pressure loss, large range, high accuracy, and almost unaffected by parameters such as fluid density, pressure, temperature, viscosity, etc. when measuring volumetric flow rate under working conditions. No movable mechanical parts, therefore high reliability and low maintenance. The instrument parameters can remain stable for a long time

Turbine flowmeter: It is a speed type instrument with high accuracy, good repeatability, simple structure, few moving parts, high pressure resistance, wide measurement range, small volume, light weight, low pressure loss, and easy maintenance. It is used to measure the volume flow rate and total amount of low viscosity gases in closed pipelines. It has a wide range of practical value in industries such as petroleum, chemical, metallurgical, and urban gas pipeline networks. A turbine flowmeter is an instrument that uses a multi blade rotor (turbine) to sense the average flow velocity of a fluid and derive the flow rate or total amount from it.

The main principle difference between vortex flowmeter and turbine flowmeter:

The vortex flowmeter is designed and manufactured based on the Karman vortex principle. The principle of fluid oscillation is applied to measure flow rate. When the fluid passes through the vortex flow transmitter in the pipeline, two columns of vortices proportional to the flow velocity are alternately generated up and down behind the vortex generator in the triangular column. The release frequency of the vortices is related to the average velocity of the fluid flowing through the vortex generator and the characteristics of the vortex generator.

Turbine flowmeter is a flow measurement obtained by cutting magnetic induction lines through the rotation of the impeller to output signals, and then processing and outputting the signals. Vortex street is a flow measurement obtained by detecting Karman vortices and processing output signals. Turbine flowmeter is the main type of velocity flowmeter. Its principle is that when the measured fluid flows through the turbine flowmeter sensor, the impeller rotates under the action of the fluid, and its speed is proportional to the average flow velocity of the pipeline. At the same time, the blades periodically cut 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, namely an electric pulse signal, is induced in the coil. The frequency of this electric pulse signal is proportional to the flow rate of the measured fluid. Simply put, it is similar to a household water meter. When the medium moves, it pushes a wheel to rotate, allowing the flow rate to be calculated based on the rotation.
