[0002] Metal rotor flowmeter is a type of variable area flowmeter. In a vertical cone that expands from bottom to top, the gravity of the float with a circular cross section is borne by the liquid power, and the float can rise and fall freely in the cone. It moves up and down under the action of flow velocity and buoyancy, and after balancing with the weight of the float, it is transmitted to the dial to indicate the flow through magnetic coupling. It is generally divided into glass and metal rotor flowmeters. Metal rotor flowmeters are the most commonly used in industry. Glass materials are usually used for small-diameter corrosive media. Due to the inherent fragility of glass materials, key control points are also made of precious metals such as titanium.

Therefore, when the conical tube of the metal rotor flowmeter needs to be maintained and cleaned, the left conical tube and the right conical tube can be separated, thereby making it easier to clean the inside of the conical tube. However, it is inconvenient to install and fix one side of the flowmeter body, and it is difficult to fix the flowmeter body to the wall or the ground, which affects the stability of the installation and fixation of the flowmeter body.
