In a rotameter the flow is measured at
WebIn the variable area flowmeter (sometimes known as a Rotameter), the differential pressure across a variable aperture is used to adjust the area of the aperture. The aperture area is then a measure of the flow rate. The instrument is reliable and cheap and is used extensively throughout industry, accounting for about 20% of all flowmeters sold. WebJul 1, 2014 · Variable-area flowmeters, often called a rotameters, are a cost-effective solution for liquid and gas flow measurement. Notably, external power isn’t required for operation. The meter delivers a fail-safe flow rate under any circumstance. The variable-area flowmeter is called a rotameter because the float spins, or rotates, as the flow passes ...

Web1) shaped float. 2) fixed orifice. 3) magnet. Differential Pressure Switch. a flow switch consisting of a pair of pressure sensing elements and an adjustable spring that can be set a specific value to operate an output switch. When gas flow is measured, the measuring instrument must be mounted ____ the flow element. below. WebMay 2, 2024 · May 4, 2024 at 20:22. The characteristic length for a small object (such as a sphere) is sqrt (A). If you take velocity as volumetric flow rate / area then the Re = Q/ (vsqrt (A)), with Q as flow rate and v as kinematic viscosity of water. This can be solved for A in terms of the Reynolds number, A = (Q/ (vRe))^2.

A rotameter is a device that measures the volumetric flow rate of fluid in a closed tube. It belongs to a class of meters called variable-area flowmeters, which measure flow rate by allowing the cross-sectional area the fluid travels through to vary, causing a measurable effect. See more The first variable area meter with rotating float was invented by Karl Kueppers (1874–1933) in Aachen in 1908. This is described in the German patent 215225. Felix Meyer founded the company "Deutsche … See more A rotameter consists of a tapered tube, typically made of glass with a 'float' (a shaped weight, made either of anodized aluminum or a ceramic), inside that is pushed up by the See more • Due to its reliance on the ability of the fluid or gas to displace the float, graduations on a given rotameter will only be accurate for a given substance at a given temperature. The main property of importance is the density of the fluid; however, viscosity … See more • A rotameter requires no external power or fuel, it uses only the inherent properties of the fluid, along with gravity, to measure flow rate.
