Hydrostatic equilibrium states that the pressure at any point in a fluid at rest is equal, and its value is just the weight of the overlying fluid. The usual range of pressure that falls for this device is around 0.2 MPa or 2 Kg/cm 2. Following are the three different types of manometers: Simple manometers; Differential manometers; Micromanometer; Read also: Pressure Gauges: Types, Working, Applications and more . A manometer is a device that can measure pressure. The inclined manometer is frequently called a Draft Gage because it is widely used for determining the over-fired draft in boiler uptakes and flues. In Figure 11.15(a), both sides of the tube are open to the atmosphere. If the manometer … Parts of the manometer This level is called the meniscus. manometer To calculate pressure in a U-tube manometer, add the sum of the readings above and below zero.

A closed-end manometer is a U-shaped tube with one closed arm, one arm that connects to the gas to be measured, and a nonvolatile liquid (usually mercury) in between. 1. Because atmospheric pressure changes with distance above or below sea level, a barometer can also be used to measure altitude. The manometer is filled with Hg (specific gravity 13.6) & the liquid above the Hg is CCl4 (s.g 1.6). An anemometer is a device used for measuring wind speed and direction.It is also a common weather station instrument. tube manometer for vertical instruments and gives much greater magnification when the limb is inclined. Interpretation: The principle behind the working of barometer and manometer has to be explained. If the valve is opened the reading of the manometer falls to. ... Also called sphygmanometer. Of them all, one of the most important is a device called a Manometer. U-gauge synonyms, U-gauge pronunciation, U-gauge translation, English dictionary definition of U-gauge. 3 x 10 5 Nm 2. It is the Device used for measuring the difference of Pressures, between two points in a pipe. All these types of manometers are discussed briefly below. A line of one foot is a monometer, 2 feet is a dimeter, and so on--trimeter (3), tetrameter (4), pentameter (5), hexameter (6), heptameter (7), and o ctameter (8).
