Metal rotameter is a kind of variable area flowmeter.

In a vertical cone tube expanded from bottom to top, the gravity of the float with circular cross section is borne by the liquid power, and the float can rise and fall freely in the cone tube. Under the action of velocity and buoyancy, it moves up and down, after balancing with the weight of the float, it is transmitted to the dial to indicate the flow through magnetic coupling.

The metal rotameter is suitable for small caliber and low flow medium flow measurement; it is reliable in operation, small in maintenance and long in service life; the requirements for straight pipe section are not high; the wide flow ratio is 10:1; the double line large LCD display, optional on-site instantaneous / cumulative flow display, with backlight single axis smart indication; non-contact magnetic coupling transmission; the metal rotameter is all metal structure, suitable for high temperature High pressure and strong corrosive medium; can be used in inflammable and explosive dangerous situations; optional two-wire system, battery, AC power supply mode; multi parameter calibration function; metal rotameter with data recovery, data backup and power failure protection function
