What is the viscosity range of liquids measured by a turbine flowmeter?

1. Working principle of turbine flowmeter

Turbine flowmeter is a flowmeter based on the principle of fluid vortex. Its main components include magnetic turbines and sensors. As liquid passes through the turbine, the turbine rotates at a speed proportional to the liquid's flow rate. By detecting the rotation speed through the sensor, the flow rate of the liquid can be calculated.

2. Liquid viscosity suitable for turbine flowmeter

Turbine flowmeter is suitable for measuring liquids with viscosity between 0.5-200 mPa·s. However, the accuracy of a turbine flow meter can be affected by the viscosity of the liquid within the specified viscosity range.

For high-viscosity liquids, such as syrup, sauce, asphalt, etc., the turbine flowmeter needs to be adapted through special structural design and shovel turbine, and the impact of liquid flow on the turbine needs to be considered. Turbine flow meters are also suitable for low viscosity liquids such as water, alcohol and solvents.

3. Application fields of turbine flowmeters

Turbine flowmeters are widely used in chemical, pharmaceutical, petroleum, food, beverage, water treatment and other industries. It can measure the flow of different media such as single-phase liquid, gas and liquid, liquid and solid mixture.

IV. Advantages and Disadvantages of Turbine Flowmeter

Turbine flowmeter has the advantages of fast response, high accuracy, and can adapt to different media and high temperature and pressure. But it also has some shortcomings, such as being sensitive to changes in liquid viscosity, susceptible to the influence of medium particles, and susceptible to flow and vibration.

5. Summary

The turbine flowmeter is a general flowmeter suitable for measuring the flow of various liquids, but it is necessary to pay attention to the impact of liquid viscosity on its accuracy. In practical applications, it is necessary to select and debug the specific medium, and use it in conjunction with other flow meters to obtain more accurate data.
