ABSTRACT:
A liquid level measuring device for a container is disclosed. The liquid level measuring device has an elongated frame with a lower end insertable into the liquid in the container. Mounted on the frame is a buoyant floats. The floats and frame are constructed so that the floats is movable along the frame by the buoyant forces of the liquid in the container. The measuring device has a manually operable means for selectively holding the floats in a fixed position relative to the frame so that the frame and floats can be withdrawn from the liquid and the level of the liquid read by comparing the position of the floats in relationship to scale indicia on the frame. The elongated frame is made of a plurality of telescopically arranged sections so that the frame can be collapsed to a minimum length for storage and, when the device is to be used for measuring, the frame sections are moved to expand the length of the frame to the total length of the device. Furthermore, the manually operable means for selectively holding the floats in a fixed position relative to the frame includes an elongated flexible guide tape having one end attached to the section of the frame forming the lower end of the frame and having its other end connected to a coiling means mounted on the upper frame section. Several different embodiments of buoyant floats are disclosed. Also disclosed is an attachment to the collapsible liquid measuring device for obtaining samples of the liquid being measured as well as the temperature of the liquid.
