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).

specifically a gauge pressure transmitter that is referenced to atmosphere, would be mounted at the zero point. In this example, a tank of water with a level of 200 inches will exert twice the pressure than a tank of water with level of 100 inches. When liquid level measurement is needed in a closed (pressurized) tank, a gauge pressure will not work.

Why Propane Tanks Do Not Have Pressure Gauges Hunker
A full propane tank contains mostly liquid propane, with a pocket of propane gas at the top near the valve. When you open the valve, that gas gets pushed out by the pressure inside the tank. As the pressure in the tank decreases, some of the liquid propane will change back to a gaseous form until the pressure rises again.

The pressure had dropped to 0.5 bar in less than one hour. Then I went out to the boiler to check the pressure on the expansion tank and it was at over 2 bar! The floor round the boiler seemed damp too. I turned on the heating to get some hot water (which seems to have worked), and went out to check the pressure at the expansion tank again.
Vacuum Pressure: What is it & how do you measure it?
by Tom Lish. Absolute pressure is measured relative to high vacuum (0 PSIA). It is referred to as pounds per square inch (absolute) or PSIA. The electrical output of an absolute pressure transducer is 0 VDC at 0 PSIA and full scale output (typically 5 VDC) at full scale pressure (in PSIA).
