In a rotameter the flow is measured at
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 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 …

Flowmeters measure the rate of flow for a liquid or a gas. Totalizers measure the cumulative flow volume. Flowmeter/totalizers display both the flow rate and the ... 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.
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. WebMethane concentrations measured 0.3 m (1 ft) from the roof and face of the box cut were used to estimate face airflow quantities. Fresh air flow rates of 1.89 ... (5 cfm) using a rotameter. The 5 cfm flow rate provided methane concentrations in the gallery that were easily recorded by the methane monitoring instrumentation.
WebThe Fluid Flow system uses tap water supplied from a large holding tank on the third floor of the Unit Ops lab. The pressurized water flows down under gravity to the pipe network on the first floor. The water flow rate at the inlet of the network can be measured by a rotameter. The inlet pressure can be measured by a pressure gauge. WebJun 21, 2024 · Rotometer, also known as Float Type Flowmeter, is widely used in industry. It can measure the flow of liquid, gas and steam, and it is suitable to measure the flow of small and medium pipe diameters (DN4 ~ 250). The rotor flowmeter measures the fluid flow according to the throttling principle. But it changes the flow area of the fluid to keep ...
