Metal Tube Rotameter

Metal Tube Rotameter : It 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 annulus area created by ‘Float’ position. The position of the float is sensed by a magnet and indicated on the dial in terms of flow rate.

Operating Principle : Metal Tube Rotameter is basically a variable area flowmeter. The diffrential Pressure across the annulus area is constant and the Flowrate is measured as a function of the position of annulus area created by float position.
