Abstract: A system, apparatus and method for monitoring the status and use of an LP fuel tank using cellular communication technology. The system includes a sensor unit communicatively connected to a storage tank, the sensor unit measuring the level of fluid in the storage tank and transmitting fluid level data externally via a cellular data communication link, a remote host unit disposed remotely from the storage tank, the host unit receiving fluid level data from the sensor unit via the cellular data communication link, and a base unit disposed in the vicinity of the storage tank by a user, the base unit receiving fluid level data from the sensor unit via the cellular data communication link or via an RF link.

Abstract: An apparatus for monitoring an article or system, particularly an LP or propane tank, includes a transmission unit, a base unit and a host unit. The transmission unit is disposed on or near the article or system and detects at least one parameter related to the article or system and send information related to the detected parameter. The base unit is disposed at a predetermined location remote from the article or system. The base unit receives information related to the detected parameter from the transmission unit. The host unit is disposed at a location remote from the base unit and the transmission unit. The host unit receives information related to the detected parameter from the base unit for management purposes. A method of monitoring an article or system such as a fuel tank is also disclosed.
