◆ Metal tube flowmeter ◆
● Model : F821 series
● Description :
Metal tube rotameter is basically a variable area flow meter. The differential pressure across the annulus area is constant and the flow rate is measured as a function of the position of annulus area created by float position. The position of the float is sensed by a magnet and indicated on the dial in terms of flowrate.
