Variable area flow meter

FLOW

Flowmeters are very simple yet versatile flow measurement devices for use on all types of liquids, gases and steam. It is a type of differential pressure (DP) flow meter. They operate on the variable area principle, whereby a flowing fluid changes the position of a float, piston, or vane to open a larger area for the passage of the fluid. The position of the float, piston, or vane is used to give a direct visual indication of the flowrate.
