ABSTRACT:
A system for sensing the surface level of flowable material within a container, comprises a drop weight secured to a cable through a pulley for being disposed above the material and brought into contact with the surface level of the material. The cable is wound and anchored to a spool driven by a reversible motor. A transducer operably secured to the pulley provides an output responsive to the strain on the cable exerted by drop weight. A signal processor connected to the transducer generates an output signal responsive to the drop weight being supported by the material. A pulse generator for generating a plurality of pulses the number of which is proportional to the amount of rotation of the spool. A programmable controller drives the motor a forward direction to lower the drop weight toward the material surface and in the opposite direction to raise the drop weight substantially the same distance after the processor has detected that the drop weight has landed on the material surface and for calculating the surface level of the material based on the number of plurality of pulses generated by the pulse generator during rotation of the spool in the forward and reverse directions. A display is connected to controller for displaying the calculated level of the material surface. A method for sensing the material level within a container is also disclosed.
