System and method for spatially resolved determination of at least one physical or chemical process variable

A system for a spatially resolved determination of at least one physical or chemical process variable of a flowable medium arranged in a container in an automation system, comprising:

• a sensor that is movable in the medium and/or in the container, wherein the sensor is configured to ascertain information about the at least one process variable;
• a position determination unit configured to supply information about a current position of the sensor relative to the medium and/or to the container;
• and
• a data transmission unit configured to collect the information about the respective current position of the sensor and the corresponding information supplied by the sensor about the at least one process variable and/or to communicate the information to an external control unit and/or display unit.

A method for a spatially resolved determination of at least one physical or chemical process variable of a flowable medium arranged in a container in an automation system, the method comprising:

• providing a system for the spatially resolved determination of the at least one physical or chemical process variable, the system comprising:
• a sensor that is movable in the medium and/or in the container, wherein the sensor is configured to ascertain information about the at least one process variable;
• a position determination unit configured to supply information about a current position of the sensor relative to the medium and/or to the container;
• and
• a data transmission unit configured to collect the information about the current position of the sensor and the corresponding information supplied by the sensor about the at least one process variable and/or to communicate the information to an external control unit and/or display unit;
• during a commissioning phase of the automation system, the sensor suppling information about the at least one process variable from a plurality of positions within the container and/or the medium;
• using the information about the at least one process variable to determine a plurality of relevant positions with which the deviation of the information about the at least one process variable exceeds a predefined threshold value;
• and
• in a subsequent operating phase, the sensor moving between the relevant positions in order to provide information about the at least one process variable.
