An instrument for measuring gas pressures. A mercury or oil manometer measures gas pressure as the height of a fluid column the gas sample is able to support. Open manometers measure gas pressure rela [..]

1730, from French manomètre (1706), said to have been coined by French mathematician Pierre Varignon (1654-1722) from Greek manos "thin, rare; loose in texture, porous; scanty, few" (see mon [..]

An instrument for measuring differences of pressure. The weight of a column of liquid enclosed in a tube is balanced by the pressures applied at its opposite ends, and the pressure difference is compu [..]

A manometer is a scientific instrument used to measure gas pressures. Open manometers measure gas pressure relative to atmospheric pressure. A mercury or oil manometer measures gas pressure as the hei [..]

(n) a pressure gauge for comparing pressures of a gas

A tube filled with a liquid used to measure pressures.

A tube filled with a liquid used to measure pressures.

a tube filled with a liquid used to measure pressures.

an instrument for measuring pressure liquids and gasses. It usually consists of a U-shaped tube containing a liquid, the surface of which is in one end of the tube; moves proportionally with changes i [..]

An instrument used for measuring the pressure of liquids and gases.

Instrument that measures pressure and elastic pro­perties of gases. Barometer and steam gauges are examples.

A pressure-sensing device that displays pressure differences between two locations by the level of a colored liquid. Two types of such manometers (including a U-tube and a curved inclined manometer) are commonly used as pressure gauges and permanently mounted on ASD installations.

An instrument for measuring pressure. Usually, a manometer is a glass tube filled with a liquid that is used to measure the difference in pressure across a flow measuring device, such as an orifice or [..]

An instrument that measures air pressure differences between locations. Tubes are usually attached to a manometer and run to the spaces where pressures are measured. Essentially a U-tube partly filled [..]

A Manometer is an instrument for measuring pressure of gases and vapors. Gas pressure is balanced against a column of liquid in a U-shaped tube.

A U-shaped tube filled with the specific liquid. The difference in height between the liquid in each leg of the tube gives directly the difference in pressure on each leg of the tube. Used to monitor differential pressure.

 An instrument for measuring air pressure; the amount of displacement of a liquid indicates the pressure being exerted on the instrument. 

Instrument to measuring pressure of gases and vapors. Gas pressure is balanced against column of liquid such as mercury, in U-shaped tube.

An instrument for measuring pressure; essentially a U-tube partially filled with a liquid, usually water, mercury or a light oil, so constructed that the amount of displacement of the liquid indicates [..]

An analog or digital instrument that measures the static air pressure differential between two or more adjacent areas.

an instrument used for the measurement of gaseous pressures or pressure differentials in a system.

A tubular device for measuring fluid (or vapour) pressures. A liquid or is introduced into the tube, the level of which is determined by fluid pressure; height of the liquid may be read from a scale.

A device to measure small to moderate pressure differentials. Device is general constructed from glass or plastic tubes filled with water, oil, alcohol or other suitable fluids.

An instrument for measuring pressures: especially a U-tube partially filled with a liquid, usually water, mercury, or a light oil, so constructed that the amount of displacement of the liquid indicate [..]
