Rotary Flow Meter with Three-Axis Scraper

Rotary Flow Meter with three-axis scraper, also called three-rotor flow meter. It is a positive displacement flow meter, also called a positive displacement flow meter.

1. The accuracy of the flow meter has nothing to do with the viscosity of the fluid:
2.TWS low-viscosity three-rotor flowmeter instrument can accurately measure media with a viscosity <2mPa.s;
3. The standard type can measure media of 2~200mPa.s;
4. The high-viscosity type can measure media of 200 to 350,000 mPa.s according to different environments;
5. Temperature changes will not damage the accuracy of the instrument;
6. Because all key components of the TWS three-rotor flowmeter instrument have a common expansion coefficient. When the medium temperature is -40℃~+80℃, it can be accurately measured without correction.
7. The applicable medium temperature can be as high as 350℃.

Three-Axis Scraper Rotary Flow Meter Description

Sino-Inst Rotary Flow Meter (also known as “three-axis scraper flow meter”), the product model is TWS. It is a positive displacement flow meter, also known as a positive displacement flow meter. It can continuously measure the liquid in a closed pipe flow.

TWS three-axis scraper Rotary Flow Meter is mainly composed of two parts: measurement and accumulation. The flow meter machine has low friction, long service life, and strong adaptability to viscosity changes. It is widely used in the transit trade of various crude oil and refined oil products. Measurement of settlement.

The flow meter can provide on-site indication. It can also be connected to an explosion-proof pulse or 4~20mA transmitter for remote measurement to achieve automated control.

Rotary Flow Meter Working Principle

The measuring chamber of the three-rotor flowmeter consists of a cylindrical cavity and three rotors that rotate synchronously. The three rotors are installed in the cylindrical rotor chamber. The leak-proof rotor gear is installed at the end of the leak-proof rotor, and the displacement rotor gear is installed at the end of the displacement rotor. Through such a gear rotation structure, the three rotors can keep rotating synchronously.

The number of teeth of the leak-proof rotor gear is twice the number of teeth of the rotor gear for each displacement. Therefore, the rotation speed of the leak-proof rotor is half the rotation speed of the rotor for each displacement.

When the fluid flows into the measurement chamber, the three rotors rotate synchronously. The fluid is divided into three parts by the three rotors. As the rotor rotates, the fluid in the measuring chamber moves simultaneously until it is discharged.

Since the volume of the measuring chamber is known, the same volume of fluid is discharged every time the rotor rotates. By measuring the number of rotations of the leak-proof rotor, the flow rate of the fluid passing through the measuring chamber can be accurately measured.

The rotation of the leak-proof rotor is transmitted to the counter through the gears on its rotating shaft and other transmission shafts for counting and outputs a standard pulse signal.
