Read： 160 Time：20months ago Source：Transform the World with Simplicity

Turbine flowmeter is a thermodynamic instrument that uses turbine rotation to measure fluid flow. It is suitable for liquid and gas flow measurement, can be used for cold water, hot water, steam, oil, natural gas and other fluid measurement and control. Turbine flowmeter has the advantages of high precision, good stability and low pressure loss of fluid, so it is widely used in the field of industrial automation. The principle of the

turbine flowmeter is that when the fluid passes through the impeller, the impeller will receive a certain amount of inertial force to make it rotate, and at the same time convert the angular velocity of the rotation into electrical signals for output. The fluid flow can be obtained by calculating these signals. Specifically, when the fluid enters the flow channel through the turbine flowmeter, the impeller will rotate. The angular velocity of the rotation is proportional to the flow rate and is subject to inertia, so the change of the angular velocity reflects the change of the flow rate.

In the application, the turbine flowmeter is usually combined with the signal processor, which can realize the flow display, record, control and alarm. For example, in process control, different production processes can be realized by controlling medium flow through turbine flowmeter. In the chemical industry, turbine flowmeter can be used to monitor the reaction link and adjust parameters such as feeding amount and energy consumption to optimize production efficiency. In municipal water conservancy, turbine flowmeter can be used to measure and control water supply and drainage to ensure urban water supply and environmental protection level.

In general, as an excellent flow measurement instrument, turbine flowmeter has simple and reliable principle, high precision, fast response speed, long service life, and a wide range of applications. We believe that in the future of industrial automation and flow measurement, turbine flowmeter will have a more important position and application prospects.
