ABSTRACT:
A system for monitoring the level or amount of a material within a container is provided. The system includes a detection mechanism that can be a direct detection mechanism or any of a number of indirect detection mechanisms. When the detection mechanism senses an upper level of the substance in the container that is below a predetermined lower limit for the substance, the mechanism operates an alarm mechanism to emit an audible and/or visible alarm to alert an individual to the low level of the substance within the container. The alarm mechanism can be integrally formed with the detection mechanism, or can be spaced from the detection mechanism in order to provide a more accessible point for the viewing or hearing of the alarm emitted by the alarm mechanism.
