Background

The rotor flowmeter measures the fluid flow according to the throttling principle, but it changes the flow area of the fluid to keep the differential pressure above and below the rotor constant, so it is also called variable flow area constant differential pressure flowmeter, also called float flowmeter, in a vertical taper pipe expanding from bottom to top, the gravity of the float with circular cross section is born by the liquid power, the float can rise and fall freely in the taper pipe. The float moves up and down under the action of flow velocity and buoyancy, and after the float is balanced with the weight of the float, the float is magnetically coupled to the dial to indicate flow. And are generally classified as glass and metal rotameters. The metal rotameter is the most commonly used in industry, and for corrosive media with small pipe diameters, glass is generally used, and due to the fragility of the glass, the rotameter made of precious metals such as all titanium materials is also used as a key control point.
