What is a manometer used for?

Manometers are used in a variety of laboratory applications to measure the pressure of gases and liquids and also in the field of medicine.

What is a manometer used to measure?

A manometer is an instrument that measures pressure. Manometers originally were constructed to measure pressure by examining the heights of liquids in a contained shape, but now manometer commonly refers to all types of pressure measuring instruments. The simplest manometer is a thin tube shaped like a “U”.

How to use a manometer for gas?

A digital manometer is powered by a chargeable battery and you have to ensure you have properly inserted it into the slot provided.

You will find a power button on the front side of the manometer. Hit the button and turn your device on.

As soon as you turn on the manometer,it will start measuring the current air pressure and provide you with a reading on its display screen.

You must go through the user manual of the digital manometer to verify the tubing your barbed connections fit.

For obtaining differential pressure,you need to connect the positive port to the higher pressure and the negative port to the lower pressure.

The ‘Unit’ button on the manometer allows you to change the pressure measuring units easily.

The ‘Store’ key on the face of the digital manometer will save your results in the built-in memory of the device for later use.

How to read a manometer?

● The reference level is indicated by a mark on the tube. Measure the distance between the rise in liquid on one side…

● Convert the result to inches. Water is considered to be standard manometric liquid for this conversion.

● The pressure to be measured in Pascal can be obtained as follows:

N

Pressure in N/m2 = ρ X g X h

N

where, ρ = density of…
