So we are just killing fish not terrorist. Not on a military vessel, just a large At Sea Fishing Trawler / Processor. Hi Mark, Thanks for your kind comment's, although I am not really doing anything for you out here unless you eat a lot of fish.
Anyway keep up the good fight, and please let us know how it turns out. We have a system that shoots a burst of air into the tank and a measurement is calculated from that. Also just a thought, is the pressure transducer you are using classified for hazardous locations / rated to be submerged in Jet Fuel? Onboard the ship I work on we are subject to a very strict criteria as to what we can and cannot use to measure level in our fuel tanks. Is the tank vented to atmospheric pressure or is it a sealed tank under pressure? What temperature fluctuations will the liquid in the tank be subject too? Is the tank perfectly level or slightly tilted toward the suction line of a pump? And as TConnolly pointed out the tank is probably not a perfect cylinder. From the reading I have done you will still have many factors that come in to play and can add variables to your calculation if your measurements have to be exacty precise. Hopefully others will be able to help you with specific questions, as I am still trying to wrap my head around this, its interesting though. Calculate WC from psi: Formula for Calculating Volume: Then you will still need to convert cubic inches into gallons. Here are a couple of links I found, hope they will help you out.

Semendyayev, Gerhard Musiol, Heiner Mühlig. The pi (π) is approximately equal to 3.14159265359 and represents the ratio of any circle's circumference to its diameter, or the ratio of a circle's area to the square of its radius in Euclidean space. l arc is the length of the arc of the side surface of a fluid, where the fluid comes in contact with the circular base of the horizontal cylindrical tank.This is the angle that draws a half of the side arc with length ½l arc) The first radial line intercects the top surface of fluid, and the second radial line coincides with the line of the depth of fluid h. α is the angle created by 2 radial lines.How to find the radius of a horizontal tank?.How to find the diameter of a horizontal tank?.How to find the length of arc created by rotating radius r from the left‐most to the right‐most point of fluid within a horizontal tank?.How to find the angle that draws a half of the side arc of fluid within a horizontal tank?.What is the valid range of values for the depth of fluid?.How to find the area of the total surface of fluid in a horizontal tank?.How to find the area of the bottom surface of fluid in a horizontal tank?.How to find the area of the top surface of fluid in a horizontal tank?.Note, this side of fluid comes in contact with the circular base of the horizontal cylindrical tank.Ī side = r² ×(π ⁄ 2−arcsin(1−h ⁄ r))−(r−h)× √ h×(2×r−h) How to find the area of the side surface of fluid in a horizontal tank?.How to find the amount of fluid in a horizontal tank of a cylindrical shape?.About this page: Horizontal tank calculator.
