Abstract: An apparatus for determining or monitoring at least one process variable which comprises a sensor element, measuring electronics, at least one control/evaluating/calculating unit arranged removed from the measuring unit and/or an in/output unit arranged removed from the measuring unit and the control/evaluating/calculating unit. The control/evaluating/calculating unit and the in/output unit are connected with the measuring unit via a first interface, respectively a second interface, wherein the measuring electronics operates the sensor element and forwards the measurement signals via the interfaces to the control/evaluating/calculating unit as unprocessed, raw, measured values, and wherein the control/evaluating/calculating unit arranged removed from the measuring unit determines, improves and/or monitors the process variable based on the raw, measured values and makes such available via the in/output unit.

Abstract: The invention relates to an orienting mechanism (20), with which, even in the case of unfavorable installation conditions at the container (10), a fill level measuring device (16) can be mounted on the container (10) and aimed, such that the line (17) of measurement is perpendicular to the surface (14) of a medium (13) to be sensed. The orienting mechanism (20) enables the pivoting of the measuring device (16) while yet providing a reliable sealing of the interior of the container.
