Description
The Variable Area Flow meter is an instrument for measuring the flow of liquids or gases in pipelines. It includes a vertical tube through which the fluid flows whose diameter increases from the bottom to the top and a float which can move vertically in the tube. As the flow increases this float moves to a higher position until its resistance to the fluid flow is balanced by the float’s buoyed weight in the fluid, a value which is constant and independent of the flow rate. The position of the float is a measure of the flow rate. The flow rate values can be read on a scale.
