Metal Variable Area Type Flow Meter are designed to measure flow rate of liquids and gases undercritical conditions. It consists of a tapered metal tube, an indicating assembly and float. A magnetencapsulated in float couples with rotating magnets are connected to an indicating pointer. Henceforth,the movement of the float is accurately indicated in terms of flowrate.They are intended for application where high pressure, temperature or corrosive conditions precludethe use of conventional glass tube. These are all Metal Variable Area Type Flow meter design to measureflow rate of Liquids & Gases under critical conditions. It consists of a tapered metal tube, an indicatingassembly and a float. A magnet encapsulates in float couples with rotating magnets connected to anindicating pointer, thus the movement of the float, is accurately indicated in terms of flow rate.2. Working PrincipleWhen fluid or gas flows through a taper tube containing a float, a pressure difference of P1 and P2 iscreated between upper and lower side of the float. The float moves upwards by a force obtained bymultiplying the pressure differential by the maximum cross-sectional area of the float.Based on Bemoulli's theorem, the principle mentioned above can be theoretically expressed asfollows. Due to taper tube, as the float moves upwards, the fluid passing area increases as a result of which thedifferential pressure decreases. Upward movement of float stops when the dead load is dynamically balanced by the differential pressure. Tapering of metering tube is so designed that the vertical movement of the float becomes linearly proportional to the rate of flow and the scale is provided to read the position of the float, thusgiving birth to flow rate indication.

Metal Tube Rotameter is a Variable Area Flow Meter. It consists of a tapered tube, typically made of steel with a 'float', made of SS or PTFE. The differential pressure across the annulus area is constant. The float moves through the tapered tube up and down with respect to fluid flow. The vertical position of the float as indicated by scale is the measure of the instantaneous flow rate.
