Inclining the tube manometer increases the accuracy of the measurement.

U tube manometer diagram. We use the same data as in the example above except that the u tube is inclined 45 o. If dm is the manometric fluid density d1 is the density of the fluid over the manometer p2 is the atmospheric pressure for general measurement of gas pressure and p1 is the gas pressure and also if d1 dm then the differential pressure can be obtained by. The pressure exerted by the flow presses against.

Along the tube s middle portion are graduations. It is made from a u shaped tube of liquid in which the difference in pressure acting on the two straight sections of the tube causes. A few conditions where this device may be specifically employed are discussed in this article.

A simple u tube manometer is shown below. A user places the manometer in a gas draft flow. A u tube manometer is used for measuring fluid and gas pressures under different conditions.

The manometer is used to measure the pressure which is unknown by the balancing gravity force and acceleration due to gravity g 9 81 m sec2. Working operation of venturi meter. This manometer consists of a u shaped tube in which the manometeric liquid is filled.

In its simplest form a manometer is a u shaped tube consisting of an incompressible fluid like water or mercury. What was the open end before is now connected to a different pressure so that we measure the difference. Example differential pressure measurement with an inclined u tube manometer.

The pressure difference head can then be expressed as. The method of using a u tube manometer for measuring liquid under moderate pressure liquid under vacuum gas under pressure or gas under vacuum are studied here and explained through neat illustrations. U tube manomerter theory explanation diagram working equations construction of u tube manometer.

Differential u tube manometer fig. The graduations are commonly hundredths of an inch depending on the manometer s manufacturer. Openings are provided at the entry and throat at sections 1 and 2 in the diagram of the venture meter for attaching a differential pressure sensor u tube manometer differential pressure gauge etc as shown in the diagram.

2 12 is very handy to measure the pressure difference directly and is basically similar to the u tube manometer discussed above. It is inexpensive and does not need calibration. A manometer measures the pressure acting on a column of fluid.

As seen in the figure the u shaped tube filled with liquid measures the differential pressure i e the difference in levels h between the two limbs gives the pressure.
