Hydrostatic tank gauging utilizes up to three pressure sensors and one or more temperature elements. The hydrostatic pressure (liquid head) is measured; as the height increases the pressure increases as well. If a single pressure sensor is used, a manual density measurement is required for an inventory calculation.

What is automatic tank gauging system?

Automatic tank gauge systems, or ATG's are excellent additions to your fleet's maintenance program. An ATG is an electronic component placed within an above or below ground tank that monitors fuel or lubricant volume over time to assess whether the tank is leaking fluid.

How does a Pneumercator work?

Pneumercator hydrostatic tank gauging systems operate on the principle that the pressure at the bottom of the tank varies with the liquid head. The pressure balance which is equal to the tank liquid height is converted into tank contents and indicated on a calibrated dial.
