ABSTRACT:
A method and a system for detecting the level of fluid in a container is provided: The level meter includes first, second and third generally parallel probes being positioned within the container. The first probe includes a first portion that is at least partially covered by an insulating material, and a second generally exposed end. The second probe is generally free of the insulating material and the third probe provides an electrical ground. An electronic unit is operable to measure electrical characteristics of the first and second probes to determine an amount of the second probe which is exposed to a fluid within the container.
