gauge
A compound gauge is a pressure gauge that displays both negative and positive gauge pressure measurements. Gauge pressure is a measurement of pressure relative to ambient pressure. For example, if ambient pressure was 14.7 PSI and you were to measure absolute vaccum using a compound gauge, the gauge would indicate -14.7 PSI.
Around 10 PSI if you have a 2 horsepower pump. It will vary, depending on the restrictions in the exit line. Pool Masters
Pressure gauge
44.7 psi
ANY tire gauge measures air pressure in PSI.
8 PSI min - 80 PSI max
Zero (0) gauge pressure equals 14.696 PSI on the absolute scale. A lot of people will round up to 14.7 PSI for simplicity. 14.696 PSI is the pressure that is developed at sea level due to the weight of our atmosphere. The absolute pressure scale is based on zero being a perfect vacuum. Gauge pressure takes into account the atmospheric pressure at sea level (14.696 PSI). A simple conversion formula is PSIG+14.696=PSIA.
We tried to gauge the superficial damage. The pressure guage displayed the PSI in the tire.
1050 feet of water = (1050 * 0.433527) 455.2 psi gauge pressure

Your pressure gauge may be broken....If it fluctuates, then you know its not your gauge, but if your gauge always reads 80, it may need to be replaced.
