Calculating Tank water level by pressure gauge 2

[evanske]

At my steam plant we have an old 20' demin storage tank with no level transmitters on it just some tygon tubing set up to try to see the level but it is very hard to see it plus the tubing has to be cleaned to see the water clearly. I wanna just put a 0 to 10 psi pressure gauge on the bottom of the tank to get the level that way. I know a foot of water is .433 psi. My question is if the gauge reads 5 psi what do i have to multiply it by to get the level of the tank? Thank you.

Use the inverse of 0.433, or 2.31.

Or............buy a gage that reads in feet of water.

He didn't say he wanted the level in feet.

Multiply the pressure reading by 2.3.
5 x 2.3 = 11.5ft.
