ABSTRACT:
An electromechanical filling level measuring apparatus for the intermittent measurement of the filling level in a container with the help of a measuring tape that is wound on a spool driven by an electric motor and to the lower end of which a sensing weight is secured. Switching means are provided for the reversal and for the switching off of the electric motor that respond respectively when the sensing weight encounters the surface of the filling medium during paying-out of the measuring tape and when an upper limiting position is reached during the winding-in of the measuring tape. A detector device determines and indicates the length of the measuring tape paid out or wound in. A housing is fitted to the top of the container and is divided by a barrier wall into a measuring tape chamber containing the measuring tape spool, that is in communication with the interior of the container by way of a through-guide for the measuring tape and a chamber containing the electric motor, the switching devices and the detector device. On the underside of the housing is a fixed guide sleeve, in which a tube through which the measuring tape passes is mounted for limited vertical movement against the force of a spring, a carrier for the tube being fastened to the end of the measuring tape. The tube consists of metal and extends out of the upper end of the guide sleeve into the measuring tape re chamber, in which there is provided an inductive proximity switch so arranged within the range of movement of the metal tube as to respond to its passage.
