With the function "Echo curve memory" the echo curve can be saved
at the time of setup. This is generally recommended; for using the
Asset Management functions it is absolutely necessary. If possible, the
curve should be saved with a low level in the vessel.
With the adjustment software PACTware and the PC, the high
resolution echo curve can be displayed and used to recognize signal
changes over the operating time. In addition, the echo curve of the
setup can be also displayed in the echo curve window and compared
with the actual echo curve.
The following circumstances cause interfering reflections and can
influence the measurement:
l High sockets
l Vessel installations such as struts
l Agitators
l Buildup or welded joints on vessel walls
Note:
A false signal suppression detects, marks and saves these false
signals so that they are no longer taken into account for level
measurement.
This should be done with a low level so that possible interfering
reflections can be detected.
Proceed as follows:
1 Select the menu item "Additional settins" with [->] and confirm with
[OK]
. With [->] you have to select the menu item "False signal
suppression" and confirm with [OK].
2 Confirm again with [OK].
3 Confirm again with [OK].
