First Claim
1. An apparatus for monitoring the fluid fill level in a tank of the type having a fill level gauge with a rotatable magnet in a gauge head, comprising:
- (a) a transmission unit adapted to be disposed on or near the tank, the transmitter being constructed and arranged to detect at least the fill level of the tank and send information related to the detected fill level, the transmission unit comprising a Hall effect sensor which mates with the head of the tank fill level gauge and tracks the rotational position of the magnet in the gauge head;
(b) a base unit adapted to be disposed at a predetermined location remote from the tank, the base unit being constructed and arranged to receive information related to the detected fill level from the transmission unit; and
(c) a host unit adapted to be disposed at a location remote from the base unit and the transmission unit, the host unit being constructed and arranged to receive information related to the detected fill level from the base unit.

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.

16. An apparatus for monitoring and managing the fill level of a propane or LP fuel tank of the type having a fill level gauge with a rotatable magnet in a gauge head, comprising:
-
(a) a transmission unit adapted to be disposed on the fuel tank, the transmitter being constructed and arranged to detect at least the fill level of the fuel tank and send information related to the detected fill level, the transmission unit including; (i) a battery power supply, (ii) a controller connected to the power supply, the controller including a power management system for sending information to the base unit only when predetermined changes in the fuel tank being monitored occur or when predetermined environmental factors are sensed, (iii) a sensor connected to the controller and communicatively coupled to the fuel tank being monitored, the sensor being comprising a Hall effect sensor which mates with the head of the tank fill level gauge and tracks the rotational position of the magnet in the gauge head, and (iv) a radio frequency transmission send element connected to the controller; (b) a base unit adapted to be disposed at a predetermined location remote from the fuel tank, the base unit being constructed and arranged to receive information related to the detected fill level from the transmission unit, the base unit including; (i) a power supply, (ii) a controller connected to the power supply, (iii) a radio frequency transmission receive element connected to the controller for receiving information from the transmission unit, (iv) a telephone line interface connected to the controller and adapted for connection to a telephone line for sending and receiving information to and from the host unit, (v) a sensor connected to the controller, and (vi) a display connected to the controller for displaying information pertaining to the fuel tank being monitored; and (c) a host unit adapted to be disposed at a location remote from the base unit and the transmission unit, the host unit being constructed and arranged to receive information related to the detected parameter from the base unit, the host unit including; (i) a computer, (ii) a telephone line interface connected to the computer and adapted for connection to a telephone line; and (iii) software resident in the computer for managing information related to the detected parameter.

17. A method of monitoring the fluid fill level in a tank of the type having a fill level gauge with a rotatable magnet in a gauge head, comprising the steps of:
-
(a) detecting at least the fill level related to the tank at the location of the tank, the detecting comprising the steps of mating a Hall effect sensor with the head of the tank fill level gauge and tracking the rotational position of the magnet in the gauge head via the sensor; (b) sending information related to the detected parameter to a predetermined first location remote from the tank, and (c) sending the information related to the detected fill level from the first remote location to a second location remote from the tank and from the first remote location. - View Dependent Claims (18, 19)

20. A method of monitoring a fill level of a propane or LP fuel tank of the type having a fill level gauge with a rotatable magnet in a gauge head, comprising the steps of:
-
(a) detecting at least the fill level related to the tank at the location of the tanks, the detecting step including the sub-steps of; (i) mating a battery powered Hall effect sensor with the head of the tank fill level gauge, and (ii) tracking the rotational position of the magnet in the gauge head via the sensor; (b) sending information related to the detected fill level to a predetermined base location remote from the tank via radio frequency transmission, (c) receiving via radio transmission, storing and displaying the sent information related to the detected fill level at the base location; (d) sending the stored information related to the detected fill level from the base location to a host location remote from the tank and from the base location via a telephone link; (e) receiving, via the telephone link, the sent information related to the detected fill level at the host location; and (f) storing and processing the information related to the detected fill level at the host location.
