5.4 Echo curve analysis
The echo curve represents the tank, as seen by the radar transmitter. Each peak corresponds to
a reflection of the radar signal - the surface of the level, an obstacle, or something else. By
viewing single instances or movies of the echo curve, how and why the transmitter behaves as it
does can be understood, and it can be configured accordingly to achieve a reliable level
measurement. Usually, an echo curve analysis is not needed; the transmitter automatically sets
the appropriate parameters based on the start-up information, such as tank height, and tank
media, etc. However, it is a very valuable tool for troubleshooting difficult applications.
