what are the different kinds of instruments that measures pressure?

The answer lies within.

Method One = Anamometer\nMethos two + Pitot - static pressure\n\nAnamometer is one of the familiar devices that looks like three cups mounted on their side and they drive a shaft to gauge the wind speed.\n\nA pitot static system is a method where a tube pointed into the wind collects "ram air" and compares the pressure differential to a static port mounted perpendicular to the wind.\n\nI prefer the latter of the two beccause there are no moving parts and their in no calibration needed generally.

an anameter  -it is used fr measuring current passing through the circuit.\n\n conical flask -its flat bottemed used to hold liquids in reactions where heating is not required.\n\nburette -used to add one solution to another and also acurately measures the amount of liquid used.\n\ndropper pipette -used to add small but accurate amount of liquid to another.\n\nfunnel - used to carry out filtration.\nboiling tube-made of thick resistant glass used fr strong heating.\n\nround bottemed flask-used to hold liquids in reations where heating is required.\n\nwatch glass-holds solids\n\nevaporating dish-it can be gentely heated\n\nmortar and pestle-fr grinding and mixing solids\n\ngud luck!hope it helps

balances, beakers, and pipettes.

I have used the Bernoulli equation to calculate pressure drop through piping and to size pumps (determine required head pressure).  You can't get much more real than that.

Pressure, Temperature, and Mass.  That's just three basic things to measure.  You measure volume, from volume you get density, which is an intensive property.  Pressure is an intensive property.  Temperature is an intensive property.  Volume and mass isn't because if you partition them, they will not be the same, unlike pressure or temperature (assuming there is no temperature gradient), and density.  From these, you could get stuff like entropy, gibbs free energy, figure out work, thermal conductivity, enthalpy, etc.  You just have to look for the right stuff.

I suppose you are reffering to the small digital scales. They have a device whos electrical resistance changes under pressure.

There is indeed a standardized method of measuring rain. The soure below has detailed information about how it is made. There are also other rain gauges, such as weighing gauges and a tipping bucket gauge. They're described in the other source.

Standard sea level barometric pressure is 1013 Millibars. When the needle goes above this, it indicates a High pressure. When the needle drops below, it indicates Low pressure.\nGo to a weather page like http://www.wunderground.com/global/CI_Index.html\nIt will tell you the pressure.

It's called a flow meter.

simply use a hydrometer.

If it is a high-volume, low pressure pump, one of the easiest ways is to get a long piece of clear tubing and make a U-tube manometer.  the pressure will cause the water to climb in the tube vented to the atmosphere, while the other end is connected to the pump outlet.  You measure the height of the water column, and can get the head directly in feet of water, a popular unit of measurement in the pump industry.  If it is a high pressure pump, a simple pressure gage from the local plumbing supply or hardware store will read in PSI.  In rough terms, 14.7 psi is approximately equal to 32.2 Feet of water column pressure.

As you go back in time, the electrical measurements were not always measured with a digital display.\n\nWhen you are using an analog device - the measurement or reading was shown by a needle or indicator - which is designed with an electro-mechanical principle - based upon electrical deflection in a magnetic field and has been calibrated with a spring loaded element. The springs in pressure gages as well as electrical devices are not always perfectly linear and have a chance to be sticky at the low end ( that is why they always ask you to tap these devices lightly before taking a reading ). Therefore to reduce this error the measurements in analog meters were moved to 4-20 mA, 10-50mA, 1-5 V etc.\n\nHowever with a digital readout device there is no such need, but the continuity wherever it exists is based on the analog measrement history.\n\nThe same is applicable to the pneumatic devices where the signals are of very low pressure vaues such as 3 -15 or 3 -27 psig etc.

Anywhere there is a difference in pressure. Examples:\nLow pressure in a vaccum cleaner, higher pressure outside pushes the air into the cleaner. Different pressure in a house compared to outside, when you open a window the higher pressure flows to the lower pressure. Remember that it is always a push and never a suck. Science never sucks!
