Precision Tank Test System

The Alert Model 1000/4000 UST Test System is a mass based system for measuring tank leakage.  It uses a patented mass measurement technique using the buoyancy force measurement of a displacement probe.  Changes in buoyancy force are directly related to changes in the mass of product in the tank.  Measuring mass change eliminates the need for correcting for product temperature expansion and contraction.

The Alert Model 1050 Series UST Ullage Test System is a microprocessor controlled test method which uses a transducer to record signals measured in the tank during the test.  The transducer is inserted into the tank through the fill pipe or other opening and is positioned just below the top of the tank.  The tank is monitored at atmospheric pressure to determine the background noise level.  The tank is then pressurized to 1.5 PSIG, or may be depressurized to 0.5 PSIG and monitored for the sound of air passing through an opening.

Alert Model 1000 Underground Storage Tank (UST) Test System is a 2 part system.  The Underfill System and the Ullage Test System together make up the Alert Precision Tank Test System.
