How many types of rotameter are there?

Area meters are of two general types : Rotameters and. Piston type meter.

Which instruments are used by the principle of venturimeter?

venturimeter working principle:- Venturimeter is an instrument which is used to measure average velocity of a flowing fluid or flow rate of a flowing fluid. The venturimeter is attached to a pipe using flanges so that the fluid which is flowing through the pipe also flows through a venturimeter.

What is venturimeter explain with diagram?

A venturimeter is a device used for measuring the rate of a flow of a fluid flowing through a pipe. It consists of three parts. shows a venturimeter, through which water is flowing. The speed of water at X is 2 cm/sec.

What is rate of flow meter?

in engineering, an instrument for measuring the flow rate, that is, the volume or mass of a medium passing through the instrument per unit time. Rate-of-flow meters are used to control and monitor liquids, vapors, and gases during production, distribution, consumption, and storage.

What is A rotameter and how does it work?

A rotameter is a commonly used type of industrial flowmeter that is used to measure the flowrate of a liquid or gas. It consists of a tapered tube with a float inside. Rotameters work in a simplistic way: fluid raises the float when it passes through the tapered tube. When there is no flow, the float stays resting at the bottom.

Why is the inside of A rotameter cone shaped?

However, as the inside of the rotameter is cone shaped (widens), the area around the float through which the medium flows increases, the flow speed and drag force decrease until there is mechanical equilibrium with the float’s weight. Floats are made in many different shapes, with spheres and ellipsoids being the most common.

What materials are used in A rotameter float?

The glass type is used for gas and liquid, metal tubes are used for opaque liquids. The rotameter float could be constructed of metals of various densities it could be lead to aluminum, glass, and plastic types are also used. Mostly stainless steel floats are used.

Why is viscosity important in A rotameter?

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 may also be significant.
