Rotameter flow meter

- Jan 24, 2018 -

Rotameter is a kind of variable area flowmeter, in a vertical cone from the bottom up, the circular cross section of the float gravity is supported by the liquid dynamic, the float can freely rise in the cone And fall.


main application

Metal rotor flowmeter for small diameter and low flow media flow measurement; reliable, small amount of maintenance, long life; less demanding for straight pipe; wide flow ratio of 10: 1; large dual-line LCD display, optional site Instantaneous / total flow display, with backlight uniaxial sensitive indication; non-contact magnetic coupling transmission; metal rotor flowmeter all-metal structure, suitable for high temperature, high pressure and highly corrosive media; can be used in flammable and explosive hazardous situations; Select two-wire system, battery, AC power supply; multi-parameter calibration function; metal rotor flowmeter with data recovery, data backup and power-down protection.
