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.Know More
The simplest manometer is a thin tube shaped like a "U". The tube contains a known liquid, like water. This design measures the pressure difference between two areas, or airflows. The difference in the liquid height between the two sides could be measured, and using the density of the liquid, the pressure difference could be calculated.
Since then, many more complex manometers have been designed to measure pressure in a wide variety of situations.Learn more about Measurements
A moisture meter is an instrument that is designed to detect the level of moisture in various building materials. It can measure the moisture content of materials such as wood, tile, fiberglass, roofing and plaster.Full Answer >
The tube of the manometer is partially filled with mercury or water which settles in the bottom of the u-shaped tube, before the atmosphere being measured is allowed to enter the open end of the tube and move against the fluid in the tube. The difference in the height of the liquid in the sealed side and open side of the tube is the measure of the pressure of the atmosphere or gas being tested.Full Answer >
A psychrometer is an instrument that measures the amount of humidity in an atmosphere. The instrument uses two thermometers which, when compared, determine relative humidity.Full Answer >
