Function (Fct.)
Input Range Description
1.5.0 APPLICAT.
(Application)
For difficult applications. See also
BM100 A Service Manual.
1.5.1 LEVEL
(Level Threshold)
Press ENTER to access
and modify the threshold
value using the display.
Warning : Critical Parameter 2.71 GAIN 1
This function acts as a filter. Real-time
gain and reflection amplitude are
displayed along with threshold value.
Refer to Section 3.4.7 to correctly set
the device.
Enter value. 0 to probe
length. 1.5.2 DIST. INPUT
(Distance Input)
No value
This forces the device to look for the
product in a particular zone measured
from the flange facing : enter an
estimated value if there is no level
signal. Do not enter the dead zone.
Enter value. Maximum
value = Fct. 1.1.2 – 150
mm (6 in) unless Fct.
1.1.2 is higher than 150 1.5.3 DETE. DELAY
(Detection Delay)
0.0
This forces the instrument not to
analyse reflections in a defined zone
immediately below the flange.
Modification of the maximum value:
increase Fct. 1.1.2 Hold Distance.
1.5.4 INTERF. LEV **
(Interface Level
Threshold)
Press ENTER to access
and modify the threshold
value using the display.
Warning : Critical Parameter 2.86 GAIN 1
This function acts as a filter and may
be lowered if interface reflection is
difficult to detect.
Real-time gain and reflection
amplitude are displayed along with
threshold value.
Refer to Section 3.4.7.
Enter value from 1.05 to
99 1.5.5 EPSILON R **
(Dielectric Constant)
2.5 or as in order
This configures the dielectric constant
value for use in interface applications
and TBF mode.
Enter value from 0 to
probe length 1.5.6 INT. INPUT **
(Interface Distance
Input)
No value
As for Fct. 1.5.2 but for interface
measurement.
Select YES or NO 1.5.7 SETTLING **
NO
For decanting processes & mixed
products that separate over time.
YES : For decanting processes
NO : For when 2 products are
immiscible (remain separated)
Select YES or NO 1.5.8 C.I.P.
(Cleaning In Place) NO
If YES is selected and the signal is
lost, the gauge will search for a
reflection along the whole length of
the probe rather than the designated
measurement zone. This allows a
reset to be made following a cleaning
cycle. If the gauge doesn’t find a
reflection or the reading is frozen at
the end of the probe then the tank
hasn’t been filled or drained.
1.5.9 MODE
(Application Mode)
Select DIRECT.MODE,
MANU. MODE or TBF.
Never use MANU.
MODE.
Warning : Critical Parameter DIRECT MODE
This is used for setting the
measurement mode automatically
(direct or TBF). Note that TBF mode is
not available if the gauge is
configured for interface. Contact
KROHNE for more information on
TBF measurement.
