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.
Claims10
Apparatus for continuous measurement of the liquid level in a container having a floor, particularly a fuel tank of a motor vehicle, wherein a flexible, multiple-strand band cable is secured to the container and is an oscillation-determining element of an oscillator, the output of which communicates with a device to be operated thereby, such as a control or display stage, and wherein the length of the sensor is larger than the length required for the sensor to reach to the floor of the container, said sensor having at least a portion thereof doubled upon itself to define an arc or loop at the floor of the container, and support means engaging the sensor and holding the arc or loop means in constant, predetermined relationship relative to the container floor.
Apparatus as claimed 5, wherein the element is formed as a tube and the sensor is arranged within the element.
