Metal rotor flowmeter
Product Detail



Metal rotor flowmeter

Wuxi oubai electromagnetic flowmeter is manufactured with the latest technology of contemporary electromagnetic flow and has the following characteristics:

Metal rotor flowmeter is a kind of variable area flowmeter. In a vertical conical tube which is enlarged from bottom to top, the gravity of the round cross-section float is borne by the liquid power, and the float can rise and fall freely in the conical tube. It moves up and down under the action of velocity and buoyancy, and after balancing with the weight of the float, it is transferred to the scale to indicate the flow through magnetic coupling. Generally divided into glass and metal rotor flowmeter. Metal rotor flowmeter is the most commonly used in the industry, for small pipe diameter corrosive medium is usually made of glass, due to the fragility of the glass material itself, the key control point is also useful for precious metals such as titanium rotor flowmeter material
