Note on numbering format
Owing to the technical limitations of our computer operating system and the tabular calculation software
used for the present document, numbers are shown in the continental European format rather than in
the standard anglophone manner, i.e. commas are used in lieu of decimal points and vice versa.
For example:
Anglophone format: 1,000.00
Continental European format: 1.000,00
In the transmitter display, however, numbers that are four or more digits long are shown without separat-
ing commas but with decimal points, as follows.
Example: 1000.00

4. Applications
The electronic module type KDSE is a transmitter with integrated magneto electric measuring element for
measurement of floater’s actual position or and transmission of actual pointer position into an electrical
signal.
The electronic module has to be assembled inside an enclosure with connector with a degree of protec-
tion of min. IP20 (EPL Gb) resp. IP54 (EPL Db). This enclosure and the connector should by sufficient for
the use (EPL).
5. Operational mode and system design
The microprocessor controlled KDSE transmitter is used in flowmeters series KDS and BGK. The position
of the float is transmitted to the pointer axle by means of a magnetic system. The KDSE measures the
field of a magnet mounted on the pointers axle and generates an output current of 4 to 20 mA from it. The
scale is generally non-linear and is linearized in the process with a minimum of 16 interpolation points.
This points and the measuring range is defined by manufacturer while calibrating the complete instrument.
The earth’ magnetic field and moderate homogeneous external magnetic fields are largely compensated.
Float magnet cause influence the transmitter KDSE’s measurement of pointer position. The correct cur-
rent output is supplied only if the pointing is moved by the float. Turning only the indicator leads to diver-
gent values, however, it permits a tendentious check of the instrument.

7. Special conditions for safe use
7.1 Environmental influences on the electronics
Environmental influences on the built-in transmitter type KDSE how the process temperature must be
taken into account. See Chapter 14 of the general operating instructions for the meter type or KDS BGK.
7.2 Atmospheric conditions
In accordance with EN 1127, a “potentially explosive atmosphere“ is defined as a mixture of air and com-
bustible gases, vapour, mist or dust under atmospheric conditions. Such conditions are defined in EN
13463-1, para. 1, with values Tatm = -20 °C to +60 °C and Patm = 0.8 to 1.1 bar. Outside this range, safe-
ty parameters for most ignition sources are not available.
Usually, variable-area flow meters operate under operating conditions outside the atmospheric conditions
of 0.8 to 1.1 bar. Irrespective of the zone classification –safety parameters of explosion protection –are
basically not applicable to the inside of the measuring tube.
Therefore operation with combustible products is only allowed if a potentially explosive air mixture is not
formed inside the flow meter. Where this condition is not met, the operator will need to assess the ignition
hazard in each individual case and give due consideration to existing parameters (e.g. pressure, tempera-
ture, process product, materials of construction for the measuring tube).
7.3 Ground connection
In variable-area flow meters, it is possible under operating conditions for charge separation to occur in the
measuring tube due to the transport of non-conductive fluids and/or when the flow comes into contact with
non-conductive internals (e.g. liners, floats).
For that reason, variable-area flow meters must be permanently grounded by the operator by way
of the process connections (flanges) in order to discharge electrostatic build-up. The operator is also re-
sponsible for extending the ground continuity of the process pipeline.
If grounding cannot be made via the process connections (plastic process connections or undefined con-
nections), the flow meter must be connected to the local ground potential via the flanges. This connection
only ensures electrostatic grounding of the device and does not meet the requirements for equipotential
bonding.
7.4 Electrostatic charge of non-conductive parts
In hazardous areas of protection class IIC pay attention to the risk of the electrostatic charge in a danger
threatening amount at cleaning works of the synthetic material housing and glasses.
Devices where explosive electrostatic charges can be expected to be generated due to cleaning
action are marked with an adhesive label:
WARNUNG- / WARNING-
Gefahr elektrostatischer
Aufladung! Nicht reiben!
Danger of electrostatic
charge! Do not rubb!
To clean these devices use a wet wipe.
7.5 Mechanical strength
The flow meters have undergone an impact test to EN 13463-1 for a low level of mechanical hazard.
Additional protective measures are required if there is a higher mechanical hazard level.

The electronic module is marked as follows:
When the module is assembled in a variable area flow meter is additional a mark on the scale of the de-
vice.
