Remote sensor module of type Radar

Radar (301443): module for determining water levels of fresh, dirty and gray water via distance measurement using a radar sensor.

Several measurement values are recorded for each of the remote measurement channels. Their name is made up of the variable part and a fixed part which depends on the type of sensor module it is assigned to (e.g. "myName - Level", "myName - Distance", etc. for sensor modules of the type "Radar").

The selected colour is also The selected colour is also displayed in the "Measurement System" configuration section via the icon photo in the sensor module status information area. The colour caps make it easier to distinguish sensor modules of the same type when several are used

Sensitivity is increased by moving the slider to the right. For larger distances or poorly reflective surfaces (empty overflow basin covered with mud), this can improve the reliability of the measurement. For short distances or highly reflective surfaces, however, reducing the sensitivity may improve the reliability of the measurement.

Possible causes for loosing the work point::

• No sufficiently high amplitude deflections
• Distance could not be determined (underflow detected)
• The starting point of the measurement window has jumped to the start of the measurement range

The threshold value is displayed as a black horizontal line in the echo curve display area.

Days on which no echo curves have been created are greyed out in the control element for date selection (click on the calendar symbol next to the date). If no echo curve has been recorded for a manually selected day, the echo curve at the time closest to the selected time will be displayed.

By clicking and holding the mouse button, a section can be selected within which an automated filter curve will be created. The next available filter will be used for that. If all 5 filters are already used, no action is carried out. When creating the filter curve, the 5 reference points are first distributed symmetrically on the x-axis (distance). The amplitude (y-axis) of the 5 reference points is set to the value that corresponds to the echo curve at the x-position of the respective reference point. The reference points can be adjusted further by clicking and moving them in the graphic or by entering the distance and amplitude values in the area for manual input of the reference points..

By clicking and holding the mouse button, you can select an area to be enlarged. The zoom can be cancelled using the "Reset zoom" button displayed under the "Magnifying glass" symbol.

The area displayed by default depends on the configured mounting height. Parts of the echo curve (underneath the configured mounting height) may not be displayed.

Only amplitude values above this threshold are included in the echo curves.

The 5 reference points can be adjusted by clicking and holding the mouse button, provided the zoom function or the mode for the automated creation of filter curves are deactivated.

Parts of the echo curve displayed here are usually the result of multiple reflections and should be suppressed using the filter curve.

The selected filter is highlighted by changing the background colour. If the filter is not in use, the dot next to the name is grey. If the filter is in use, the colour of the dot corresponds to the colour of the filter curve in the graphic. A pencil symbol is also displayed next to the name. After clicking again on an already selected filter, the name of the filter can be changed.
