Figure 7-15: Echo Curve
When connected to Rosemount Radar Master Plus, past measurement records and echo
curves including the 10 highest peaks, as well as the 50 last alert events are automatically
transferred from the transmitter’s internal memory to the hard drive on your local
computer. Past measurement records are then available the next time you connect to the
transmitter using the level trend timeline.
Measurement problems can be understood by studying the position and amplitude of the
different peaks. Additionally, the recorded echo curves give insight into unexpected and
intermittent measurement behaviors, for instance, at the time of the triggered alert.
