BM 102
Function (Fct.)
Input Range
Description
2.1.5.0 APPLICATION
2.1.5.1.0 THRESHOLD
2.1.5.1.1 LEV. PULSE AMP.
Read only value.
Dynamic value.
Amplitude of level pulse in millivolts.
2.1.5.1.2 LEV. PULSE GAIN
Read only value.
Dynamic value.
Amplification of level pulse (gain 0, 1,
2, or 3).
Enter a value from
50mV to 25000mV
2.1.5.1. THRESHOLD
500 mV G3 at 1 m
Threshold of the level pulse (in
millivolts). The threshold evolves in
terms of gain amplification factor
changing by the electronic converter.
Enter a value from
Fct. 2.1.1.4: Dead
zone to fct. 2.1.1.2:
Probe length
2.1.5.2 DISTANCE INPUT
This function forces the BM 102 to
search for the product surface in a
zone other than the actual measuring
zone. If there is no level signal, you
can enter an estimated value.
Enter a value 0mm
or 0in to Fct.
2.1.1.4: Dead zone
2.1.5.3 DETECTION DELAY
As per order
This function forces the instrument
not to analyse reflections in a zone
directly below the flange. The entered
value of the detection delay must be
smaller than the "dead zone" value.
2.1.5.4 SEARCH PROBE END
The search zone
for the probe end is
from Fct 2.1.5.3
Detection delay up
to Fct. 2.1.1.1 Tank
height.
Automatically measures the probe
length. The tank must be empty. Tak
height must be configured to a value
greater than the estimated probe
length. Measured in the units
configured in fct. 2.1.2.1.1.
2.1.5.5 RESET BM 102
Restarts the BM 102.
2.1.6.0 SERIAL I/O
Enter 0 to 15
2.1.6.1 ADDRESS
0
Sets the address of the device for
connection to a HART multidrop
network. The current output switches
to 4 mA.
0 = 4 … 20 mA output current active
1 – 15 = in multidrop mode (4 mA)
2.1.7.0 STRAP TABLE
Select m3, l, US
Gal, Ft3, bbl, M3/h,
Ft3/h, kg, Metric
Tons, US Tons
2.1.7.1 VOLUME UNIT
Liter [l]
Unit for conversion values ("volume
table"). The selected unit is used to
define the strapping table values.
0 to 20 points
2.1.7.2 INPUT TABLE
0
(i.e. no volume
table)
This function defines the strapping
table. The maximum number of points
is 20. Each subsequent value must
be greater than the previous one. The
length and volume units can be
changed later without affecting the
settings in the table. Calculations are
done automatically in the instrument.
2.1.7.3 DELETE TABLE
This function deletes the strapping
table.
