Measuring technology
The type FS/FT probes operate on the
capacitive measuring method. The
fused-in electrode strip together with
the steel tube form a capacitor, the field
lines of which run in part above the glass
surface through the product space. The
capacitance of this capacitor changes
when, in the area of the electrode, the
probe is surrounded by product, the
dielectric constants of which deviate
from air. Any change in the dielectric
constants also causes a change in the
capacitance. This capacitance change
is measured by applying a high-frequency voltage with a constant frequency to the measuring electrode.
The current flowing via the capacitor is
converted in the transmitter and used
for display by the evaluation unit. This
measuring method can be used to
detect liquid and interfacial levels, and
implement reactor full/empty indicators.

5Design
The probe consists of a glass lined steel
probe carrier with fused-in electrode
strip. The lead to the electrode strip is
also fused in and runs to the transmitter
mounted on the probe.
6
Probe FS
The FS probe is used for the measurement of filling levels, especially on storage tanks. The electrode strip has been
fused-in into the glass in parallel to the
longitudinal axis of the probe carrier.
The effective length reaches from the
lower end of the probe carrier to the
vicinity of the mounting flange. Tubes
are usually selected as probe carriers,
but baffles are also suitable. The FS
probes can be manufactured in any
required length up to 3500 mm.
7
Probe FT
The application of the FT probe ranges
from full and empty messages for tanks,
the determination of interfacial layers, up
to the protection of pumps against running dry. The electrode is designed as an
annular electrode. Pipes, flange pipes
and spacer rings are used as probe carriers.
8
Application limits
The glass line probe is equivalent to
Pfaudler apparatus glass with respect
to corrosion resistance (for more
detailed information, refer to our publication 614). The probes F FS/FT can be
used from a dielectric constant value of
approx. 6 on. The usability with small
dielectric constants has to be checked
by trial.
Assembly and wiring
9
High-voltage surface tests which
are customary for glass lined parts
are not permitted for the FS/FT
probe.
A visual inspection of the glass lining of
the probe upon receipt will be sufficient.
This inspection should be repeated
occasionally, e.g. during a downtime. If
extremely aggressive media are processed, the F probe can be checked in
glass lined apparatus with the aid of the
P probe (glass monitoring). Electrical

Note!
On leaving the factory, Liquicap M
devices are calibrated for media
with a conductivity of ≥ 100 μS/cm
(e.g. for all water-based liquids,
acids, alkalis ...). A recalibration is
only necessary if the 0 % value or
100 % value should be adjusted to
suit customer-specific requirements or if the liquid is not conductive.
13.1Installation and
function check
Make sure that all post-installation and
post-connection checks have been carried out before you commission your
measuring point:
n See “Post-installation check”
checklist
n See “Post-connection check”
checklist
13.2Basic setup
Commissioning without the
display and operating module
This section describes commissioning
the Liquicap M with the function switch
and the operating keys (–/+) on the
FEI50H electronic insert.
Note!
Only the “Wet” type of calibration can
be carried out without the display
and operating module.
During wet calibration (“Wet” operating
mode), the 0 % value and/or the 100 %
value is adjusted to customer-specific
requirements. This calibration can be
carried out if the tank is empty, full or
partially full. During full calibration, the
probe must be covered by liquid in the
installed state. An empty and full calibration must be performed.
13.2.1Function switch – position 1
Measuring operation
In normal operation, the function
switch must be set to position 1.
13.2.2Function switch – position 4
Measuring modes
m
Note
Before carrying out empty and full
calibration, the medium properties
must be configured. The “No buildup”
operating mode is set at the factory.
“Medium property” subfunction
The “No buildup” operating mode should
be set for media that do not tend to form
buildup on the probe rod (e.g. water, beverages …). As of a conductivity of 100
μS/cm on (i.e. all water-based liquids,
acids, alkalis ...), the measured value is
independent of the conductivity of the liquid (independent of concentration fluctuations.
19
Measuring probe Type FS/FT
In the “Buildup” operating mode, the
buildup compensation function integrated in the software is activated. In
this operating mode, the measured
value is independent of the conductivity
of the liquid as of a conductivity of 1000
μS/cm (independent of concentration
fluctuations).
This compensates measuring errors
caused by conductive media sticking to
the probe rod (e.g. yoghurt).
Proceed as follows to choose between
media forming buildup (e.g. yoghurt)
and media not forming buildup (e.g.
water):
n Turn the function switch to position 4
n Buildup” operating mode
– Press the + key for media that tend
to form buildup.
– The green LED confirms your entry
by flashing four times.
n No buildup” operating mode
– Press the – key for media that do
not form buildup.
– The green LED confirms your entry
by flashing four times.
13.2.3Function switch – position 2
Carry out empty calibration
(for empty tanks)
If the tank is empty (0 %), the empty calibration sets the signal current to the
lower value of 4 mA. When calibration is
completed, the current value of 4 mA is
displayed at the ammeter.
Proceed as follows to perform empty
calibration:
n Turn the function switch to position 2
nPress the – and + buttons together
for approx. 2 s until the green LED
flashes
– Release the two keys again.
– The flashing stops after approx. 5 s.
– Empty calibration is saved.
20
13.2.4Function switch – position 2
Carry out empty calibration
(for almost empty tanks)
If possible, the exact level of the tank
should be known and should not be too
large (< 30 %).
Too high a level reduces the accuracy of
the zero point (corresponds to the
empty tank). An ammeter must be connected to the current pick-off at the
electronic insert. Let us presume that
the level was determined for 15 %. Now
the current value that corresponds to
the filling level of 15 % must be determined. The lower current value can be
adjusted with the +/– keys. The + key
increases the value, the – reduces the
value. The following must also be considered:
The lower current value (= empty
1. tank, 0 %) is 4 mA.
2. The upper current value (= full tank,
100 %) is 20 mA.
3. This results in a measuring range of
16 mA for a change from 0 % to
100 %, i.e. 0.16 mA increase in the
current for every 1 % of increase in
level.
4. For a 15 % level, this is 15 % x
0.16 mA/ % which equals 2.4 mA. This
must be added to the 4 mA to achieve
the current value to be set: 2.4 mA +
4 mA = 6.4 mA.
Proceed as follows to perform empty
calibration on a partially filled tank:
nTurn the function switch to position 2
The current value can be adjusted
with the +/– keys. For this purpose,
press the + or – key for at least
2 seconds. You can set the desired
current value (> 4 mA) using the multimeter connected.
nThe empty calibration is saved when
you release the key.
13.2.5Function switch – position 3
Carry out full calibration
(for full tanks)
If the tank is full (100 %), the full calibration sets the signal current to the upper
value of 20 mA. When empty calibration
is completed, the current value of 20 mA
is displayed at the ammeter.
Proceed as follows to perform full calibration:
nTurn the function switch to position 3
nPress the – and + keys buttons
together for approx. 2 s until the red
LED flashes
– Release the two keys again.
– The flashing stops after approx.
10 s.
– Full calibration is saved.
13.2.6Function switch – position 3
Carry out full calibration
(for almost full tanks)
If possible, the exact level of the tank
should be known and should be as large
as possible (> 70 %).
Too low a level reduces the accuracy of
the upper point (corresponds to the full
tank).
An ammeter must be connected to the
current pick-off at the electronic insert.
Let us presume that the level was determined for 90 %. Now the current value
that corresponds to the level of 90 %
must be determined. The upper current
value can be adjusted with the +/– keys.
The + key increases the value, the – key
reduces the value.

Measuring probe Type FS/FT
The following must also be considered:
1. The lower current value (= empty
tank, 0 %) is 4 mA.
2. The upper current value (= full tank,
100 %) is 20 mA.
3. This results in a measuring range of
16 mA for a change from 0 % to
100 %, i.e. 0.16 mA increase in the
current for every 1 % of increase in
the level.
4. For a 90 % level, this is 90 % x
0.16 mA/ % which equals 14.4 mA.
This must be added to the 4 mA to
achieve the current value to be set:
14.4 mA + 4 mA = 18.4 mA. (You can
also take the upper current value and
then subtract 10 % x 0.16 mA =
1.6 mA from the 20 mA.)
Proceed as follows to perform full calibration on a partially filled tank:
n Turn the function switch to position 3
The current value can be adjusted
with the +/– keys. For this purpose,
press the + or – key for at least 2 s.
You can set the desired current value
(> 20 mA) using the multimeter connected.
n The full calibration is saved when you
release the key.
13.2.7Function switch – position 5
Measuring range
At the factory, the measuring range is
always calibrated to the probe length
ordered. If the electronic insert is used
in another probe, the measuring range
must be configured in accordance with
the probe length.
© Pfaudler GmbH
Proceed as follows to configure the
measuring range 2000 pF (probe length
< 6 m) or 4000 pF (probe length > 6 m):
n Turn the function switch to position 5
n Press the – button to set 2000 pF
– The green LED confirms your entry
by flashing four times.
n Press the + key to set 4000 pF
– The green LED confirms your entry
by flashing four times.

ramp up to 22 mA. This test is completed after approx. 35 s.
Proceed as follows to activate the
device self-test:
n Turn the function switch to position 6
nPress the + and – keys together to

Annex 1
A 3.1 Potentially hazardous atmospheres
The application of the FS/FT measuring
probe in potentially hazardous atmospheres belonging to zone 0 is permitted
if the following conditions are maintained: Connection to certified, intrinsically safe electrical circuit only with
type of protection EEx ia IIC with the
following maximum values Ui = 30 V Ii =
150 mA Pi = 750 mW Li negligible Ci
negligible.
The maximum allowable inductance of
all inductors = X L0 in the supply circuits
is 2.9 mH.
The maximum allowable capacitance of
all capacitors = X C0 in the supply circuit is 180 nF.
54
A 3.2 Atmospheric conditions
The process pressure of the media or
the media temperature must be between
0.8 … 1 bar or 20 … 60 for all applications that require category 1/2 equipment. If these conditions of use are not
complied with at the measuring sensor,
it must be ensured that the measuring
sensor does not heat up itself (not even
in the event of fault). Please note that
the safe operation of the plant with
respect to pressures/temperatures of
the substances used are the responsibility of the operator. The characteristic
data supplied by the manufacturer shall
be observed.
A 3.3 Equipotential bonding
Since the intrinsically safe circuit of the
measuring electrode is grounded during
operation, a joint equipotential bonding
system must exist in the course of the
entire wiring of the intrinsically safe circuit and the reactor or pipeline must be
included in this equipotential bonding
system.
A 3.4 Lightning protection
If the FS/FT measuring probe is installed
in systems that must be protected
against ignition hazards caused by
strikes of lightning, the FS/FT measuring probe must be included in lightning
protection. The lightning protection
system must comply with the requirements of VDE 0165.
