A liquid level indicating system includes a plastic link chain suspended in a container extending between a high level position and a low level position of a liquid in the container. A weighing device is positioned above the high level position of the liquid for measuring the weight of the chain. An attachment device secures a lower portion of the chain to the bottom of the container with sufficient slack so as not to affect the operation of the weighing device.

Liquid level indicating method and system

Apparatus for indicating a preselected condition of material in a vessel which includes a laid wire cable vertically suspended within the vessel so as to contact and be surrounded by material contained therein. The laid wire cable is suspended by a roller-type thrust bearing which permits free rotation of the cable and thus prevents torsional sheer stresses on the suspended cable end due to tension in the cable and consequent unraveling and reraveling of the cable lays. In a preferred embodiment of the invention wherein the upper end of the cable is selectively slackened and material level is determined as a function of weight of the slackened cable end unsupported by material, a spherical head is affixed to the cable to seat against and cooperate with a side-thrust washer slidably carried on the foot of a load cell for isolating the load cell from lateral cable forces due to material or component tolerance variations. A slip ring assembly may be attached to the cable for providing direct electrical connection thereto.

Suspended-cable apparatus for measuring a preselected condition of

A method and apparatus for measuring the level of containerized or free standing semi-solid material is disclosed. A substantially smooth uniform cable is suspended above and into the semi-solid material. A predetermined amount of slack is introduced into the cable. The slackened portion of the cable above the level of the semi-solid material is coupled to a weighing apparatus. The weighing apparatus weighs the slackened portion of the cable, the weight of such a portion being related to the amount of cable above the level of the material and thus an indication of the level of the material. Subsequent to a measurement, the cable is raised for uncoupling the cable from the weighing apparatus.
