Understanding Vacuum Measurement Units Vacaero
Mechanical vacuum gauges such as the Bourdon dial gauge (Fig. 3) read from “zero” at atmospheric pressure down to a full scale vacuum reading of 30 inches of Hg. As the pressure drops (or goes down) the vacuum reading number rises (or goes up).
Troubleshooting a bladder pressure tank
I have a shallow jet pump with a bladder pressure tank. I have pressure all the time, and the top 1/3 of my pressure tank sounds like there is air in it, so I doubt it is waterlogged. Every time I flush a toilet or turn water on for a few seconds the pump turns on, then a few seconds after I close the faucet the pump shuts off.
What's the Difference Between PSI, PSIA & PSIG?
by Dick Pansire. The recommended pressure for the tires on your car is most likely around 32 PSI G. Other factors such as barometric pressure and outside temperature can affect how inflated those tires appear, even though the number of air molecules in the tire remain the same. Most industrial applications measure gauge pressure,
Gauge Pressure, Absolute Pressure, and Pressure
The total pressure, or absolute pressure, is thus the sum of gauge pressure and atmospheric pressure: where is absolute pressure, is gauge pressure, and is atmospheric pressure. For example, if your tire gauge reads 34 psi (pounds per square inch), then the absolute pressure is 34 psi plus 14.7 psi ( in psi), or 48.7 psi (equivalent to 336 kPa).

Pressure generated by 40 foot high tank of Diesel. To determine the pressure generated by a 40 feet of Diesel, you will need to know the specific gravity (S.G.). The S.G. of Diesel varies depending on temperature and diesel type, but is the maximum often indicated by many resources. Using this calculator a 40 foot column of Diesel would convert to psi.
pressure Is negative 20 psi / 1.5 bar possible
Gauge pressure is zero referenced against ambient air pressure, so it is equal to absolute pressure minus atmospheric pressure. Negative signs are usually omitted. To distinguish a negative pressure, the value may be appended with the word "vacuum" or the gauge may be labeled a "vacuum gauge." Differential pressure is the difference in pressure between two points.

If the gauge indicates the pressure (or pressure drop) in the process, that information is valuable only if one can do something about it (like cleaning a filter) otherwise it is useless. If one approaches the specification of pressure gauges with this mentality, the number of gauges used will be reduced.

The filling loop is located on the immersion tank and there is a pressure gauge fitted there. There is an expansion tank in the garage beside the boiler and it also has a pressure gauge. I seem to lose pressure (from 1 bar to zero) in a matter of hours, according to the gauge at the immersion tank.
Pressure Gauge:
The three standard measurement techniques are gauge pressure, absolute pressure, and differential pressure. Gauge pressure is a measurement of pressure relative to ambient atmospheric pressure, while absolute pressure uses atmospheric pressure as its zero reference. Both a tire pressure gauge and blood pressure cuff measure gauge pressure.
