Abstract:
A container level sensor for mounting in a container in a generally upright orientation to sense the level of material in said container, said sensor comprising an elongate strip member having a measurable capacitance, said strip member comprising:a. a first elongate electrically conductive strip insulated from said material and from said container;b. a second elongate conductive strip insulated from said material, from said container and from said first strip;c. at least one of said first and second strips being flexible and mounted spaced from the other said strip such that the force of said material on the flexible strip causes the space between said first and second strips to be reduced so as to change the capacitance of the capacitor defined by said first and second strips; andd. a cover to prevent said material from entering said space between said first and second strips.
