The turbine flowmeter measures fluid flow by detecting the rotation speed of the turbine, and the pulse frequency is proportional to the flow rate (f=KQ).
1. Working principle of turbine flowmeter
Turbine flowmeter is a commonly used flow meter that can measure the volume or mass of fluid. The turbine flowmeter causes the turbine to start rotating by introducing fluid into the turbine chamber. The rotation speed of the turbine is proportional to the speed of the fluid. The turbine flowmeter determines the flow rate of the fluid by detecting the rotation speed of the turbine.
2. Calculation formula of pulse output frequency of turbine flowmeter
The pulse output frequency of turbine flowmeter is proportional to the flow rate of the fluid. The calculation formula is: f=KQ, where f is the pulse frequency, K is a constant, and Q is the fluid flow rate. The frequency of the pulse output of the turbine flowmeter is a fixed value, usually in the range of 100,000 to 100,000 Hz. The output signal can be used for flow recording, control and detection.
3. Application Scenarios of Turbine Flowmeter
Turbine flowmeter is an accurate and easy-to-use flow meter, which is widely used in industrial control, metering, energy management and environmental protection and other fields. Turbine flow meters are widely used for flow measurement and flow control in industries such as chemical engineering, food processing, pharmaceuticals, coatings, textiles, paper and petrochemical industries.
IV. Summary
A turbine flowmeter is a flow measurement device that determines the flow rate of a fluid by detecting the rotation speed of the turbine. The pulse frequency of the turbine flowmeter is proportional to the fluid flow, and its calculation formula is f=KQ. Turbine flow meters have the characteristics of high accuracy, easy installation and use, and have been widely used in various fields.
