A liquid level measuring device for measuring the liquid level in a container, includes a fastening member for holding the device in a container, and a support with a lower end portion or prop extending into engagement with the container bottom. The support carries a liquid level sensing member and is connected to the fastening member through a resiliently yieldable connection, whereby the support is continuously urged into a constant position relative to the container bottom, so that an accurate indication is obtained of the liquid level in the container.

A liquid level measuring device for use inside containers having different sizes and shapes, comprising: a holder for fastening the device to the top of a container; a support mounted on the holder and extending toward the bottom of the container; an electro-mechanical transducer mounted on the support; a lever rotatably mounted on the support and carrying a float for moving the lever as the liquid level changes, said lever acting upon the transducer in response to changes in the liquid level; prop means connected with the support in generally axial alignment therewith for extending into contact with the container bottom for supporting the support relative to the container bottom; resiliently yieldable coupling means connecting the support to the holder to compensate for dimensional changes between the top and bottom of the container and maintaining the prop in engagement with the container bottom so that the support is maintained in a constant predetermined spaced relation to the container bottom; and adjustble means for adjusting the length of the device to accommodate it to different size containers. In combination, a liquid level measuring device and pump, comprising: a holder for fastening the device inside a container in spaced relation to a bottom of the container; a support mounted on the holder; an electro-mechanical transducer mounted on the support; a lever rotatably mounted on the support and carrying a float for moving the lever as the liquid level changes, said lever acting upon the transducer in response to changes in the liquid level; prop means connected with the support for extending into contact with the container bottom for supporting the support relative to the container bottom, said prop means comprising a motor-driven pump means driven by conventional means for pumping liquid from the container; and resiliently yieldable coupling means connecting the support to the holder so that the support is movable in a longitudinal direction relative to the holder to compensate for dimensional changes between the top and bottom of the container to maintain the support in a constant predetermined spaced relation to the container bottom.
