  • Automatic tank gauge systems
    Patent number: 6715350
    Abstract: A level sensor mechanism for detecting liquid levels in storage tanks. A conduit is provided having an upper portion and a lower portion. The conduit may be adapted to receive a cable therein, may be substantially rigid and adapted to resist deflection. A sensor assembly body is provided and adapted to locate a level sensor therein. The sensor assembly body may be located in fixed relation to said conduit, and may be rigidly composed and adapted to resist deflection. A coupling member may be secured to said lower portion of said conduit, said coupling member fixedly securing said conduit to said sensor assembly body, said sensor assembly body being secured on said offset portion of said coupling member. The level sensor mechanism may thereby resist or eliminate deflection through the construction of the conduit, coupling member and sensor assembly body.
