Principle of Operation
The Variable Area Flowmeter measures the flow of liquids and gases using the Variable Area Principle. As fluid flows through the tapered tube, it lifts a float the height of which corresponds to the flow rate. This float movement is transferred via magnetic coupling to an external pointer, which moves over a calibrated scale to indicate the flow. The design ensures safe, accurate measurement without direct contact between the fluid and the indicator.
