Introduction to Rotameter
2011-7-12 16:23:11

Rotary flowmeter , also known as float flowmeter , is a variable area flowmeter. Rotary flowmeter structure: In a vertically tapered tube that expands from bottom to top, the gravity of the float with a circular cross section is borne by the hydrodynamic force, 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. Generally divided into glass rotor flowmeter , plastic rotor flowmeter , plexiglass rotor flowmeter and metal rotor flowmeter . Metal rotor flowmeters are the most commonly used in the industry. For small diameter corrosive media, glass rotor flowmeters are usually used. Due to the fragility of glass materials, plastic tube rotor flowmeters and plexiglass rotors are used in many cases Flow meter .
