ABSTRACT:
An apparatus for measuring the filling level of silos and similar containers has a measuring chain which depends from a cylinder and piston unit serving to raise and lower it; the chain extends through the upper opening of the container to the bottom wall of the same. A measuring device is connected in series with the arrangement mounting the chain and with the chain itself, and has a spring which is extensible and contractable in a path parallel to the series formed by the chain, the mounting arrangement for the same and the measuring device, and an indicator movable parallel to the spring path.
