摘要

The assembly to measure and/or monitor the level of a medium, in a container, has at least one motor (1) to give a torque to a rotary axis (D1) with a measurement blade (3) rotating in the container. At least one seal (5) seals the measurement blade sleeve (4) and/or the motor. At least one crankshaft (2) transmits the motor torque into blade rotation around its own axis (D2).
