WebJan 16, 2024 · A rotameter is a flow meter device that measures the volumetric flow rate of a gas or fluid. It consists of a tapered tube with a moving internal float. Sometimes known as mechanical flow meters, gravity flowmeters or variable area flowmeters. The gravity term relates to the fact the rotameter needs to be installed vertically, as the flow rate ... WebThe rotameter works by the principle of the upthrust force exerted by the fluid and force of gravity. In the variable area flowmeter, the drop rate is constant and the flow rate is the function of the area of constriction. The fluid density must be enough for the movement of the float otherwise the reading won’t be accurate.
