The working principle
of 1. rotameter
rotameter is a device that measures flow according to the rotor speed. In the device, a rotor (also called an impeller) is installed in the pipe, and when the fluid passes through the pipe, the rotor rotates. The number and shape of the rotor blades are designed according to the measurement requirements, generally 2 to 8 pieces, and the shape of the blades is usually inclined or spiral.

When the fluid passes through the rotor, the rotation will generate a vortex, and the kinetic energy of the fluid is converted into mechanical energy, so that the rotor rotates. The speed at which the rotor rotates can reflect the flow rate and flow rate of the fluid in the pipe. Flow measurement, by monitoring the speed of the rotor rotation, you can measure the fluid flow, and the electrical signal output.

2. rotameter

1, chemical industry: rotameter is often used to measure the flow of chemicals, liquids, gases and other fluids in the chemical industry and process control in the production process.

2. Pharmaceutical industry: Rotameter is used to measure the flow of liquid medicine in the drug production process to ensure the accuracy of liquid medicine addition and avoid drug waste and quality problems.

3, food processing: rotor flowmeter for powder, beverage, liquid flow measurement, to ensure the accuracy and quality of the finished product production, it is worth being widely used.

4. Water treatment: Rotameter is widely used in water treatment fields such as sewage treatment and tap water pipelines. It can be used to monitor water flow and control water pressure.

5. Air control: Rotameter can be used to measure gas flow and is widely used in the measurement of non-corrosive gases such as steam, air, and oxygen.

3. Conclusion

rotameter has a wide range of working principles and applications. It can not only improve the automation level and production efficiency of the industrial production process, but also has the advantages of high measurement accuracy, low energy consumption, and stable accuracy. Rotameter is one of the indispensable instruments in industrial production and operation.
