Abstract
Liquid levels in remote underground bulk storage tanks are read and logged at a convenient location, such as in the office of a service station. A single liquid level gage within a sturdy tamper-proof housing is connected with a select valve which communicates through tubes with the bottom portions of the remote underground tanks. Atmospheric air is pumped simultaneously to the bottom of a selected tank through said valve and to a bellows compression chamber of said gage.
