A manometer instrument is utilized for the measurement of__________________?
Show answer Hide answer
Answer: A. pressure in pipes, channels etc
Explanation
A manometer is a fluid-filled pressure measuring instrument utilizing liquid column heights to indicate pressure. It connects directly to industrial piping, fluid channels, or pressure vessels to determine internal fluid pressure. The height difference of the liquid column provides a direct, accurate measurement of the working pressure. Manometers operate on hydrostatic principles where fluid column displacement balances applied pressure forces. Common manometric fluids include water, mercury, and colored oils depending on the pressure range measured. Differential manometers measure pressure drops across flow restriction devices in industrial piping networks.
HVAC technicians use manometers to measure air duct static pressures and filter pressure drops. Chemical processing plants rely on manometers for local pressure monitoring in liquid and gas pipelines. Laboratory experiments utilize fluid manometers for accurate low-pressure and pressure-difference measurements. Measuring atmospheric pressure specifically is performed by barometers rather than general fluid manometers. Measuring very low pressure uses specialized micro-manometers or vacuum gauges instead of standard pipeline tools. Measuring velocity requires pitot tubes connected to manometers, whereas manometers measure pressure directly.
