STATUS (cont.)
Echo Confidence
Displays the confidence of level measurement received
from the QZ02L submerged sensor, or PZ15 level
sensor, on a 0-100% scale. This value is a reflection of
the percent of echoes received from pulses. Example: If
8 pulses are sent from the level sensor and only 4
echoes are received, Echo Confidence will report 50%.
This does not mean that the level is inaccurate, but
instead means the level reading could be susceptible to
a loss of reading should the conditions causing missed
pulses gets worse. Like an increase in solids or bubbles
in the flow steam.
