I'm doing a report on manometers, and I need to cite specific uses of them in industry.  I'm having trouble finding specific uses online, so any help would be greatly appreciated.

We use them to measure the crankcase pressure (slight vacuum) on medium speed diesel engines.

Manometers are used to balance airflow in heating and ventilation ductwork. Try searching AOL keywords "manometer" and "air handlers..." there is A LOT of info out there.

FITTER out

I believe Lordtrader uses a manometer.....no  wait it's a boyometer sorry.

1981

IBM launches their PC. BMW develops the first in-car computer. PacMan hits the arcades. Shuttle Columbia launched. Prince Charles and Lady Di wedded.

I use em to synchronize carburetors.. More than two, and they are a necessity..

Along the same lines, they are also used to intentionally unbalance them. In, for example, the semiconductor or biotech industries, you have "clean rooms" which have heavily filtered air to avoid contamination of whatever your working on. You have to run the clean areas at a higher pressure than the rest of the building so dirty air doesn't get sucked into the clean areas.

At the company I used to work for we used them extensively on our semiconductor equipment to measure vacuum, exhaust pressure, and air pressure.

RV service technicians also sometimes use one to test the low-pressure (post-regulator) side of a propane system — They're easy to build from common materials, and just as accurate as a cheap pressure gauge.

We use them in biohazard containment cabinets to measure the differential pressure across the HEPA filters.
Hi and low alarms are set from this value to detect filter clogs or ruptures.

Also as MadMatt said, to measure pressure differential between 'clean' (overpressure) and 'dirty' (lower pressure) areas of the production facility.

Any decent high-performance engine shop will have a flow-bench that uses a manometer to measure cylinder head flow...

I used them in undergound mining for both ventilation studies and to set up the diesel equipment.

SRM

We use them in power plants to measure pressure differences in acid taks (for cooling towers and demineralizers) and back pressure (difference in condenser vacuum and barometric pressure).

We use one to calibrate the vaccum chamber on our electron beam welder.

This is what I use them for also. They work for both pressure and vacuum.

We use to calibrate pressure relief valves using manometers.

I used one to calibrate vacuum gages at a chem lab.

Capacitance manometers are standard equipment for monitoring measuring process pressure on semiconductor plasma processing equipment.

We use them to check gas (natural or propane) pressure on gas valves in furnaces and heaters in the Air Conditioning and Heating field.
Ritchie manufacturing and maybe Robinair (SPX) corporation make them. They may have info that would be useful on theory and usage on their websites.
Hope this helps.

I use a sphygmomanometer when administering polygraph examinations.

Manometers are a low pressure/vacuum pressure measuring instrument usually graduated in inches of water ("H2O). They have many applications and if connected correctly are quiet accurate.
Go to www.thomasregister.com and do a product search for manometer...they list 104 companies that manufacture/sell them.
Hope this helped :-)

My thanks to all of you for the helpful info.

I used to use one to calibrate the bellows pressure on a chart recorder for the oil and gas industry.
