ABSTRACT:
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.
