Measurement core technology analysis: the principle of the turbine flowmeter and its application

Project Overview

Turbine flowmeter is a kind of flowmeter widely used in the field of industrial automation, which measures the flow rate by utilizing the force of the fluid on the rotor. This article will analyze the principle of turbine flowmeter and its application.

First, the principle of turbine flowmeter

The basic principle of the turbine flowmeter is to measure the flow rate by the force of the fluid on the rotor. Turbine flowmeter by the fluid conduit, rotor, photoelectric sensor and other components. When the fluid passes through the rotor in the conduit, it exerts a force on the rotor, which makes the rotor begin to rotate. By installing a photoelectric sensor on the rotor, the rotational speed of the rotor can be measured to indirectly derive the flow rate.

The rotor of a turbine flowmeter usually consists of several blades, the number of blades is usually 6 or 8, the shape and angle of the blades will also affect the measurement accuracy of the turbine flowmeter. When the fluid passes through the rotor, a series of vortices will be formed around the rotor, and the frequency of these vortices is directly proportional to the size of the flow. Therefore, by measuring the speed of rotor rotation, you can derive the flow size.

Second, the application of turbine flowmeter

Turbine flowmeter is widely used in petroleum, chemical, electric power, pharmaceutical and other industrial fields, it can be used to measure the flow of various liquids and gases. Because the turbine flowmeter has high precision, fast response, reliability and other characteristics, so it has been widely used.

The application fields of turbine flowmeter include but are not limited to:
