Analysis & Echo Suppression Menu Option
Figure 7.9
In some applications, machine parts or support bars within a tank obstruct the sensing area,
preventing proper distance or level measurement. Using the
Analysis & Echo Suppression
menu option, you can visualize and analyze all echoes received by the ultrasonic sensor from
one or a series of measurements, as well as suppress the disruptive objects in the sensing
area.
The general procedure is as follows:
1. You must first establish a connection to a sensor built into the application environment.
2. Ideally carry out multiple echo samples.
The corresponding data will then be shown in the display together with the switching
threshold of the sensor (blue line).
3. Start automatic echo suppression. If necessary, you can correct the suppression areas.
Alternatively, you can also manually set the suppression areas.
4. Finally, verify the detected settings by taking fresh echo samples.
The detected settings can be stored to/loaded from a file.
