METAL TUBE ROTAMETER

METAL TUBE
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. The position of the float is sensed by a magnet and indicated On the dial in terms of flow rate.
STANDARD FEATURES :
