Capacitive level meters CLM-70 are compact measuring devices consisting of the level meter
body and a measuring electrode. The level meter body contains measurement electronics
and a display module. The electronics measure the electrical capacity of the electrode system,
which is dependent on the level height. The level meter’s electrical output corresponds to the
capacity (level height) and the measured data are shown on the meter’s display.
The level meter can be adjusted by the display module positioned under the transparent lid.
The level meter has 4–20mA current output with HART®communication. The level meter is
power supplied using a cable connected to the terminal block located under the display and
adjustment module.
Level meters are available in several measuring electrode modications (rod and rope-type
electrodes). Electrodes may be coated with insulation, which is important for their functioning
in the case of adherent, electrically conductive and aggressive media. Rod electrodes are
also available in a version provided with a reference tube or a pair of parallel electrodes for
measuring liquids in non-conductive tanks.
All operations described in this instruction manual have to be carried out by trained
personnel or by an accredited person only. Warranty and post warranty service must
be exclusively carried out by the manufacturer.
Improper use, installation or set-up of the sensor can lead to crashes in the ap-
plication.
The manufacturer is not responsible for improper use, loss of work caused by either
direct or indirect damage, and for expenses incurred at the time of installation or
during the period of use of the level sensors.
To ensure maximum safety of control processes, we have dened the following safety instruc-
tions and information. Each instruction is labelled with the appropriate pictogram.

BASIC INFO
• The level meters with an insulated electrode are equipped with a protective cap at the
electrode end, which must be removed before installation.
• The level meters are mounted vertically into the upper lid of the tank or hopper or on xing
brackets using a welding ange for a xing nut or a Clamp-type ange.
• When installing the level meter in a metal tank or hopper, the housing is not necessary to
be grounded separately.
• In the case of installation in concrete sumps or silos, the level meter is advisable to
be installed on an auxiliary metal structure (bracket, lid, etc.) and then connected to
a permanently submerged metal object or steel reinforcements in concrete (armouring).

sunlight and must be protected
from the weather inuences. Even
so installation is in exposed places
to direct sunlight a shielding cov-
er is necessary to be tted over
the level meter (see Fig. 7).
• The level meters for high operat-
ing temperatures are equipped
with an extension. This is used to
thermally insulate the electronics
part of the meter from the high
operating temperature. The ex-
tension must not be embedded in
the insulation more than 50 mm.

• The level meter of the CLM-70_-
00 type is provided without a
measuring electrode. Therefore,
the measuring electrode is nec-
essary to be made and mounted
to the level meter body. The elec-
trode diameter must be between
8–10 mm. For connection, the
electrode must have an M8 male
thread. For the connection proce-
dure, see chapter 12, p. 22. Fig. 10: The level meter without an electrode
For the level meter of the CLM-70_-00 type, the manufacturer is not responsible for
defects related to the connected measuring electrode!
It is intended for non-conductive media only, as only a non-insulated rod or rope
can be connected.
VARIANT WITHOUT AN ELECTRODE APPLIES TO: CLM-70_-00
• It is advisable to run the cable un-
der a cable gland (sagging down-
wards). This prevents possible
ingress of moisture through the
cable gland. Rain and condensing
water can ow freely downwards,
see Fig.9.
• The cable gland and the top lid
must be suciently tightened
to prevent moisture ingress. Fig. 9: Preventing moisture from ingress
through the cable gland

8 . eleCtriCal ConneCtion
The level meter is connected to the follow-up (evaluation) device using a suitable cable with
an outer diameter of 6–8 mm by means of screw terminals located under the display module.
The recommended wire cross-section is 2× 0.5–0.75 mm2 (shielded) for the current version.
The positive pole (+U) is connected to the (+) terminal, the negative pole (0 V) to the (-) terminal,
and the shield (only for shielded cables) is connected to the ( ) terminal.
To connect a cable to the level meter:
1. Unscrew the upper lid nut.
2. Grasp the top edge of the display module and carefully slide it upwards carefully by slightly
swinging it.
3. If you are unable to grasp the display module, a small screwdriver can be used – insert it under
the edge and slightly lift the module from several sides.
4. Loosen the cable gland to pass a stripped power cable inside.
5. Connect the cable to threaded terminals, as shown in the diagram in Fig.11. Tighten the termi-
nals and cable gland rmly. For the tightening torque, see the Technical Specications.
6. Return the display module into the head until the connector is connected correctly.
7. Slide the silicone seal onto the level meter body thread and tighten the upper lid nut rmly.
Connect the cable to the downstream device.

Electrical connection can only be made in a voltage-free state!
The power supply must be designed as a stabilized source of low safe voltage with
galvanic isolation. If a switched power supply is used, its design must eectively sup-
press common mode interference. If the switched power supply is equipped with a
PE protective terminal, it must be earthed without fail!
If the sensor is to be installed in an outdoor environment more than 20 m from an
outdoor switchboard or an enclosed building, the electrical supply to the sensor must
be supplemented with suitable overvoltage protection.
In case of a strong environmental electromagnetic interference, common routing of
the signal cable with the power cable or in case of more than 30 m in length, we
recommend grounding the level meter and using a shielded cable. Ground the cable
shielding on the side of power supply or connect it to the internal connection termi-
nal of the level meter marked as , see Figs. 22 and 23 (the cable shielding should
always be connected in one point).

The time constant of the output variable lter is set here. The time constant is given in sec-
onds. The response progress of the output variable to a step change of the level is exponential.
The time constant indicates the time, within which the output value reaches approximately
63% of the maximum value.
Higher values are useful for suppressing display uctuations during rapid changes (whirling
level). Conversely, if a rapid response is required, a low damping value must be set.
The damping time can be set within the interval of 0 to 99 seconds.
SETTING PROCEDURE FOR THE LEVEL METER
The level meter must be installed properly in the tank and connected to the power supply.
Then, the basic level meter settings can be made.

1. Bring the measured medium to the minimum capacity. In the BASIC SETTINGS – MIN CA-
PACITY menu, the value of electrical capacity measured by the level meter in real time is
displayed in the upper right corner under the sign “ACTUAL CAPACITY”. This value must be
copied to the CAPACITY line. The value which is shown on the display at this minimum capac-
ity is entered in the DISPLAY line. The OUTPUT line is not editable and displays the value of
an output variable at the minimum capacity.
2. Bring the measured medium to the maximum capacity. In the BASIC SETTINGS – MAX CA-
PACITY menu, the value of electrical capacity measured by the level meter in the real time is
displayed in the upper right corner under the sign “ACTUAL CAPACITY”. This value must be
copied to the CAPACITY line. The value which is shown on the display at this maximum ca-
pacity is entered in the DISPLAY line. The OUTPUT line is not editable and displays the value
of an output variable at the maximum capacity. The conversion to the shown value on the
display and the output (current) is always linear depending on the capacity to be measured.
3. In the BASIC SETTINGS – UNITS menu, the required units for display on the main screen of
the meter display are set in the DISPLAY line. The CAPACITY line is not editable and indicates
in which units the level meter measures the capacity.
4. The time constant of the output variable lter is set in the BASIC SETTING – DAMPING menu.
B) THE SETTING METHOD AT ANY POINT WITHIN THE RANGE (if the tank cannot be completely
emptied or ooded with a medium)
1. Flood the tank to a known level H1(e.g. 15%). In the SERVICE – CAPACITY menu item, the
capacity at this known ooding (15%) can be found. This capacity is noted down and denoted
as C1 (e.g. 35 pF).
2. Flood the tank to another known level H2(e.g. 78%). In the SERVICE – CAPACITY menu
item, the capacity at this known ooding (78%) can be found. This capacity is noted down
and denoted as C2 (e.g. 126 pF).
3. The capacities at the limit points of the measuring range can be calculated using the follow-
ing formulas.
For capacity at the lower limit point of the measuring range:
CMIN = C1– H1 ∙ (C2– C1) / (H2– H1)
Example: CMIN = 35 – 15 ∙ (126 – 35) / (78 – 15) = 13.33 pF
For capacity at the upper limit point of the measuring range:
CMAX = CMIN + 100 ∙ (C2– C1) / (H2– H1)
Example: CMAX = 13.33 + 100 ∙ (126 – 35) / (78 – 15) = 157.77 pF
4. The calculated value of CMIN is to be entered into the meter’s BASIC SETTINGS – MINIMUM
CAPACITY menu in the CAPACITY line. The value to be displayed at the minimum capacity
is entered in the DISPLAY line. The OUTPUT line is not editable and displays the value of an
output variable at the minimum capacity.
5. The calculated value of CMAX is to be entered into the meter’s BASIC SETTINGS – MAXIMUM
CAPACITY menu in the CAPACITY line. The value to be displayed at the maximum level is
entered in the DISPLAY line. The OUTPUT line is not editable and displays the value of an
output variable at the maximum capacity. The conversion to the display value and the output
quantity (current) is always linear depending on the capacity to be measured.
6. In the BASIC SETTINGS – UNITS menu, the required units for display on the main screen of
the meter display are set in the DISPLAY line. The CAPACITY line is not editable and indicates
in which units the level meter measures the capacity.
7. The time constant of the output variable lter is set in the BASIC SETTING – DAMPING menu.
