Abstract

An adjustable liquid level measuring device for measuring the level of a liquid in a variety of container configurations. The device has an indicator means for mounting on a container for providing a visual reading related to the level of the liquid in the container. The device has a frame connected to the indicator means and a buoyant float adapted for floating on the surface of the liquid in the container. The device has an endless flexible chain with a first loop adjacent to the indicator means and another portion connected to the buoyant float. The chain also has a loop movably mounted on the frame so that movement of the float moves the first loop relative to the indicator means. The indicator means is connected to have an indicator dial pointer moved by the movement of the first loop. The frame has first and second elongated frame sections with the first frame section being adapted for mounting on the wall of a container and the second frame section being adapted to extend toward a position adjacent the lowest point of the interior of the liquid container. A pivotal connection between the first and second frame sections provides for 90.degree. angular displacement of the frame sections so that the device can be in an end and top reading mode on a container.

Dependent claims

In a liquid level measuring device for measuring the level of a liquid in a container, said device comprising indicator means adapted for mounting on a container for providing a visual reading related to the level of the liquid in a container;

a frame connected to said indicator means and being adapted for mounting in a container;
a buoyant float adapted for floating on the surface of the liquid;
an endless flexible transmission means having a first portion adjacent said indicator means and another portion connected to said float;
and means for movably mounting said endless flexible transmission means on said frame so that movement of said float moves said first portion of said transmission means relative to said indicator means, the improvement comprising:
said frame has first and second elongated frame sections, said first frame section being adapted for mounting within the interior of said container on the wall thereof;
said second frame section being adapted to extend to a position adjacent to the lowest point of the interior of said container;
connector means for connecting said second frame section with said first frame section for angular displacement relative to the first frame section within the interior of the container;
said means for mounting said transmission means includes means mounting said first portion on said first elongated section of said frame, means for mounting another portion of said transmission means on said second elongated section of said frame, and guide means adjacent to said connector means for guiding said transmission means when said second section is in an angularly displaced position relative to the first section.
