Thus, the features and benefits of the disclosed method apply to the discloses level measuring device accordingly. Furthermore, the control unit of the disclosed level measuring device may be a control unit according to one of the embodiments outlined above. As a consequence, the features and benefits of the disclosed method may also be applied to the disclosed level measuring device.

Moreover, the object described above is also achieved by the disclosed industrial application that comprises a container that is configured to hold a medium with a varying level. The disclosed industrial application also comprises a level measuring device which may be connected to the container. The level measuring device is configured to measure the level of the medium in the container. Furthermore, the level measuring device is configured to be installed though a method according to one of the embodiments of the disclosed method, as described above. Consequently, the features and benefits of the disclosed method may be applied to the disclosed industrial application accordingly.

Now, turning to the figures, the disclosed teaching is illustrated in further detail. FIG. 1 shows an embodiment of the disclosed industrial application 60 in which a first embodiment of the disclosed method 100 is performed. The industrial application 60 comprises a container 20 with a bottom 21 and walls 22, the container 20 being configured to hold a medium 13, which may be a liquid of a granular material. Baffles 24 are positioned at the wall 22 of the container 20 to influence the medium 13 when it is agitated. Furthermore, the container 20 is equipped with an agitator that comprises a shaft 27 that is driven by a drive 25, which may be an electric motor. Agitator blades 26 are attached to the shaft 27 which are configured to agitate the medium 13. The bottom 21, the walls 22 the baffles 24, the agitator blades 26 and the shaft 27 form functional components 23 of the container 20 which may affect an echo 14 inside the container 20.

Furthermore, the industrial application 60 comprises a level measuring device 10 that is configured to measure a current level 15 of the medium 13 in the container 13. The level measuring device 10 is configured to emit signals 12 and to receive their echoes 14. The signals may be radar signals or ultrasound signals. Correspondingly, the echoes 14 may be radar echoes or ultrasound echoes. The industrial application 60 is a part of a production process, that is not shown in further detail in FIG. 1. The level measuring device 10 is connected to a control unit 30 that is embodied as a local control unit 32. The local control unit 32 belongs to the level measuring device 10 and is configured to evaluate the echoes 14 received by the level measuring device 10. Furthermore, the drive 25 is connected to a control unit 30 that is embodied as a remote control unit 34. The remote control unit 34 is part of the control system of the production process and is configured to send control signals 35 to the drive 25. Additionally, the local control unit 32 and the remote control unit 34 are connected to each other through a communication-capable data connection 33. The local control unit 32 and the remote control unit 34 are equipped with a computer program product 50 that is configured to perform the disclosed method 100. To that end, the computer program product 50 comprises a compressing algorithm 61 and an artificial intelligence component 55, which is embodied as a neural network. The artificial intelligence component 55 serves as a feature detecting algorithm 51.

The disclosed method 100 serves for installing the level measuring device 10 into the industrial application 60. The method 100 comprises a first step 110, in which the level measuring device 10 is attached to the container 20 at its intended installation position. Furthermore, the container 20 is at least partially filled with the medium 13. In FIG. 1, the first step 110 has already been performed. A second step 120 is performed in which a signal 12 is emitted by the level measuring device 10. The signal 12 is reflected by the medium 13 and an agitator blade 26 that is positioned above the level 15 of the medium 13. The reflected signal 12 forms an echo 14 which is captured, i.e. received, by the level measuring device 10. The received echo 14 is at least temporarily stored in a memory on the local control unit 32. In FIG. 1, the received echo 14 is shown in a diagram 40 with a timescale 41 and an intensity scale 42. The diagram 40 is arranged substantially vertically since the timescale 41 corresponds to an axis substantially perpendicular to the level 15 of the medium 13. The captured echo 14 is at least temporarily stored as a multiplicity of data points
