ABSTRACT:
A level indicator for containers is disclosed that is adapted for use in granulate storage tanks and has a laterally collapsable sleeve disposed vertically within the tank for progressive embedment in the granulate as the tank is filled. The indicator also has a flexible, longitudinally contractile member freely hung inside, and coextensive with, the sleeve. A releasable means supports the contractile member within the sleeve and as granulate flows around and collapses the sleeve against the contractile member there is provided a sensing means adapted to support the free portion of the member upon operation of the releasable means. A scale means is associated with the sensing means to record the volume of granulate in the tank.
