These instructions are supplementary operating manual for non-explosion proof meters. If you
do not have a copy of the latter instructions, please request one from Heinrichs Messtechnik
GmbH or download the instructions from our website.
The instructions herein pertain primarily to explosion proof magnetic-inductive flow meters. The technical data
in the mounting and operating instructions for non-explosion proof magnetic-inductive flow meters still apply
insofar as the present instructions do not replace them or exclude their application.
IV. Returning the device for repairs or servicing
Note: According to German waste disposal legislation, it is the owner’s or customer’s responsibility to dispose
of hazardous waste. Thus, before any devices are returned to Heinrichs Messtechnik for servicing or repairs the
following measures must be performed:
When returning the unit for an inspection, please enclose as detailed a description as possible of the fault
and the specific application, as well as the chemical-physical properties of the measurement medium.
Remove all residue of measurement medium which may be present. paying special attention to the gasket
grooves and crevices. This is especially important if the medium is detrimental to health and safety, for
example: corrosive, poisonous, carcinogenic or radioactive etc.
Costs, which result from insufficient cleaning, (disposal and/or personal injuries) will be invoiced to the cus-
tomer.

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 must be assembled in an enclosure possessing a minimum degree of protection of IP20
(EPL Gb) resp. IP54 (EPL Db). This enclosure and the connector should by sufficient for the applied (EPL).
5. Operational mode and system design
The electronic transmitter type "KDSE" is used to convert the pointer position of the mechanical measuring
system into a proportional 4-20mA signal.
The electronic module type KDSE is a "magneto-electrical angle sensor" used for recording the position or the
angular position of a magnet in the variable area flow meters series KDS and BGK. Either the position of the
float, in which there is a permanent magnet, or the angular position of a ring magnet, which is located on a
magnet tracking system, is detected directly. With the latter, the angular position of the axis with the follower
magnet serves as a measurement interface between the mechanical part and the electronics
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 mag-
net 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.

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 combustible
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, safety 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 haz-
ard in each individual case and give due consideration to existing parameters (e.g. pressure, temperature, pro-
cess 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 this 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 responsible for extending the ground continuity of the process pipeline.
If grounding cannot be made via the process connections (plastic process connections or undefined connec-
tions), 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 threat-
ening amount during cleaning work on the synthetic material housing and plastics. For cleaning purposes, use
only a damp cloth.
Devices where explosive electrostatic charges can be expected are marked with an adhesive label:
WARNUNG- / WARNING-
Gefahr elektrostatischer
Aufladung! Nicht reiben!
Danger of electrostatic charge!
Do not rub!
7.5 Mechanical strength
The flow meters have undergone an impact test to DNI EN ISO 80079-36 for a low level of mechanical hazard.
Additional protective measures are required if higher mechanical hazard levels are expected.

Only devices with ex marking may be operated within the explosive atmospheres range.
The electronic module is marked as follows:
