"distance"
Displays the currently measured distance D
display
.
"check distance"
Use this parameter to state if the displayed distance D
display
matches the real distance D. Based on
your selection, the Prosonic S automatically proposes a suitable range of mapping.
You have got the following options:
•
distance = ok
Choose this option if the displayed value matches the real distance.
After selecting this option, the
"flow N mapping"
parameter set appears. The preset range of
mapping is equal to D. That means: all interference echos which are above the current product
surface will be mapped out in the interference echo suppression.
•
distance too small
Choose this option if the displayed value is smaller than the real distance D.
In this case, the currently evaluated echo is an interference echo.
After selecting this option, the
"flow N mapping"
parameter set appears. The preset range of
mapping is slightly larger than D
display
. Therefore, the currently evaluated interference echo will
be mapped out by the interference echo suppression.
•
distance too big
Choose this option if the displayed value D
display
is larger than the real distance D.
This error is not caused by interference echos. Therefore, no interference echo suppression is
performed and the Prosonic S returns to the "flow N" parameter set. Check the calibration
parameters, especially the
"empty calibration"
.
•
distance unknown
Choose this option if you do not know the real distance D.
In this case, an interference echo supression can not be performed and the Prosonic S returns to
the "flow N" parameter set.
•
manual
Choose this option if you want to define the range of mapping manually.
The
"flow N mapping"
parameter set appears, where you can define the required range of
mapping.
"flow N mapping" (N = 1 or 2)
"sensor"
Displays the currently measured distance between the sensor membrane and the water surface.
Compare this value to the real distance in order to find out if currently an interference echo is
evaluated.
"range of mapping"
Use this parameter to specify the range of the mapping curve. Normally, a suitable value has already
been entered automatically. Nevertheless, you can change this value if required.
"start mapping"
Select
"yes"
in this parameter in order to start the mapping. When the mapping is finished, the state
is automatically changed to
"enable map"
.
