What is a manometer used for?

Because the manometer is so often used to measure pressure, the difference in column heights is also a standard unit. This may be converted to standard units of pressure using a conversion chart. It is expressed in inches or centimetres of water or mercury at a certain temperature.

What pressure does a manometer measure?

Manometers are precise devices used to measure pressure that is defined as the force produced by a gas or liquid per unit of surface area due to the effects of gravity on the weight of that gas or liquid.

What liquid is used in a manometer?

The most common fluids are alcohol, water and mercury.

Why is alcohol used in a manometer?

Because of its low density, alcohol allows for a longer column than other fluids in manometers. It also gives the inclined tube a proper meniscus.

Manometers

Manometers are used for measuring the pressure and flow in a patient's airway. Raptor Supplies offers a huge array of manometers from REED Instruments, Uniweld, Yellow Jacket and Dwyer. REED Instruments R3100 digital manometers are used to measure differential & gauge pressures up to 100 psi. These manometers provide precise measurements in 11 different units and feature a backlit LCD screen & internal memory for storing & displaying measurements. Compact gas pressure test kits from Yellow Jacket precisely set manifold pressure for LP & natural gases. These kits have brass construction ensuring high malleability and corrosion resistance. They also offer a tube nipple for smooth connection and provide pressures ranging from 0 to 10 inH2O.

Working Mechanism

A metal cylinder is a part of a metre.
When measuring gas or fluid, the meter's springy cylinder is depressed.
The cylinder is then bent, turning it into a metre, thus allowing the user to read the result.
