Rotameter luft. The Rotameter is one of the oldest and mature principles in flow measurement A float is guided inside a conically shaped tube The float rises within the tube as the flow increases This mechani cal principle is as simple as it is reliable. A device used to measure fluid flow, in which a float rises in a tapered vertical tube to a height dependent on the rate of flow through the tube 6 Working Principle  It is a variable area meter which works on the principle of upthurst force exerted by fluid and force of gravity 7. A rotameter consists of a tapered tube, typically made of glass with a ‘float’, made either of anodized aluminum or a ceramic, actually a shaped weight, inside that is pushed up by the drag force of the flow and pulled down by gravity The drag force for a given fluid and float cross section is a function of flow speed squared only.
