In a rotameter the flow is measured at

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.

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.

Working of Rotameter / Variable area flowmeter - Flow Measurement …

WebRotameters are simple, reliable and inexpensive flow measuring instruments. As a gas or liquid is introduced into a uniformly tapered flow tube a float rises, its weight supported by the fluid flowing underneath, until the entire volume of fluid can flow past the float. WebThe rotameter principle of operation is a mechanical means of flow measurement. They measure flow using a float that is able to move freely up and down within the flow tube. The buoyancy force acting on the float, the flow resistance, and the weight of the float itself are all in equilibrium. WebOct 11, 2024 · Introduction to Flow Measurement with Rotameters. The main application of the rotameter flow meter is to measure the flowrate of liquids and gases. It is composed of a plastic, metal or glass tube and float.

WebThe mass flow rate can be measured with a rotameter as shown in the figure. This exercise explains the mechanism of the rotameter. Assume that the working fluid is water with density Pw, and the density of the float is Pt, and its volume is Vt. (1) Write down the force balance equation when the float reaches a balance. WebA rotameter was designed to measure a gas flow. If the flow stopped or decreased substantially, the float (bobbin) dropped and interrupted a light beam. This triggered a low-flow alarm. The design had limitations. If the flow diminished only slightly, the light beam remained broken and the alarm light stayed on after the alarm bell was silenced ...
