ABSTRACT:
An apparatus is disclosed for the continuous measurement of the level of liquid in a container, wherein a flexible cable extends into close proximity or engagement with the floor of the container and comprises the oscillation determining element of an oscillator. The cable has a length greater than the distance between its mount to the container and the bottom of the container, and is doubled over at least part of its length to form an arc or loop at the container floor. A support engages the cable adjacent the container floor and holds the cable so that the arc or loop maintains its position relative to the container floor even though the container floor may sag or bulge, or the spacing between the floor and top of different containers varies because of manufacturing tolerances and the like.
