Abstract
A method and system for remote monitoring of liquid level within a container , such as the level of fuel within a propane cylinder. A magnetic float disposed within the container floats on the liquid , and lowers with the liquid level as fuel is consumed. Magnetic sensors outside the container sense the float as it passes in the proximity of one of the sensors . A controller receives output signals from the sensors and transmits level indicating signals to a gauge or other indicator for remote indication of the corresponding liquid level. The indicator can be located proximal the user's direct line of sight, to remind the user to periodically monitor the fuel level to prevent running out of fuel.
