Metal tube rotameter is the most commonly used rotameter in industry and laboratories. It is not only suitable for small flow measurement with pipe diameter D<150mm, but also can measure the flow of corrosive medium. But it must be installed in a vertical pipe section, and the fluid medium passes through the rotameter from bottom to top.
Application :
- Chemical plant
- Laboratory
- Liquefied Gas Station
- Natural Gas Transmission Center
- Boiler plant
Advantages
01 Suitable for flow measurement of medium with small diameter and low velocity, simple structure, low pressure loss
02 Wide flow ratio 10:1; double-line large liquid crystal display, optional on-site instantaneous or cumulative flow display.
03 Non-contact magnetic coupling transmission, suitable for high temperature and high pressure and strong corrosive medium.
04 Equipped with data recovery, data backup and power failure protection functions.
