The metal rotor flowmeter is a type of variable area flowmeter. In a vertical cone 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 freely in the cone. And drop. 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 rate through magnetic coupling. Generally divided into glass and metal rotameters. Metal rotor flowmeters are the most commonly used in the industry. For corrosive media with small pipe diameters, glass is usually used. Due to the fragility of glass, the key control point is also a rotor flowmeter made of precious metals such as titanium.
Rotameter is a variable area flow meter based on float position measurement. It adopts all-metal structure, Modular concept design, its pressure loss is small, the range ratio is large (10:1), the installation and maintenance are convenient, and it can be widely used in complex and harsh Flow measurement and process control of environment and various media conditions
The metal rotor flowmeter is suitable for measuring the flow of small-diameter and low-velocity medium; it is reliable in operation, small in maintenance, and long in life; it is not required for straight pipe sections
High; wide flow ratio 10:1; double-line large liquid crystal display, optional on-site instantaneous/cumulative flow display, single-axis sensitive indication with backlight; non-contact magnetic coupling transmission; metal rotameter full metal structure, suitable for High temperature, high pressure and strong corrosive media; can be used in flammable and explosive hazardous situations; optional two-wire system, battery, AC power supply; multi-parameter calibration function; metal rotor flowmeter with data recovery, data backup and power failure protection Features.
The metal rotor flowmeter is the most commonly used flowmeter in industry and laboratories. It has the characteristics of simple structure, intuitiveness, low pressure loss and convenient maintenance. Rotameter is suitable for measuring small flow through pipe diameter D<150mm, and it can also measure the flow of corrosive medium. When in use, the flowmeter must be installed on a vertical pipe section, and the fluid medium passes through the rotameter from bottom to top.
