Abstract
A computerized system for sensing the level of liquefied gas in a tank at a remote location and transmitting data between the location of the tank and the computer to maintain files for inventory control. A microprocessor collects electrical signals from a tank mounted transducer, which is actuated by a float gauge, and periodically sends data over telephone lines to a computer located remotely from the tank. The computer receives and processes data during time windows established for each of a group of tanks to provide current data regarding the supply of liquefied gas in the tanks.
