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.Continue Reading
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 manometer measures the difference between two different points of pressure. A manometer works by balancing the weight of a column of fluid between the two points of interest.Full Answer >
According to Reference.com, "fluid pressure" is defined as the pressure exerted by a fluid at a given depth. The weight of the liquid acting on a unit area combined with pressure acting on the surface of the liquid determines the amount of liquid pressure.Full Answer >
To measure static pressure, use a manometer with at least two pressure ports to check both the suction and discharge pressure of the duct, and add these figures together. Static pressure is usually measured in inches of water column, which is defined as the pressure exerted by one inch of water at the temperature of its maximum density.Full Answer >
To practice reading a micrometer, become familiar with the instrument, spin the ratchet with the object inside and formulate the measurement using the markings. The process takes approximately 5 minutes and requires a micrometer and an object to measure.Full Answer >
