ATG Probe Level Doesn't Match Driver's Tank Stick Level

Описание: When sticking a storage tank, you have to ensure that either pressure or vacuum has equalized inside a storage tank before you compare any electronic probe readings in the storage tank to any stick measurements that are measured through a drop tube at a gas station. The impacts of vacuum in the ullage space of the storage tank can cause a differential in the measurement of liquid within a drop tube when you have a storage system that is vapor tight, which it should be tight and without any vapor leaks especially on new installations.
