INSTALLATION
In order to ensure a high precision of the measure and good stability of
the „flow zero“ point, the transmitter must be installed into the
processed medium at least 24 H before calibration (electrode
passivation).
Dismounting precautions:
All precautions must be taken before removing the transmitter
depending on the process used as the pipe may contain dangerous /
agressive hot fluids or fluids with high temperatures or pressures.
3.1.1 Mounting positions
The 8045 electromagnetic flow transmitter can be mounted in the following ways to obtain
an accurate flow measurement although the piping should be designed to ensure that the
pipe is maintained full at all times to avoid inaccurate measurement.
Mounting horizontally
Mounting vertically
●When mounting vertically ensure that the flow direction is in an
upward direction as indicated by the arrow.
●Always mount the transmitter upstream a possible injection point in
the pipe of a high-conductivity product (acid, base, saline,...).
It is advisable to mount the transmitter at a 45°angle
to the horizontal centre of the pipe as shown in the
diagram to avoid having deposits on the electrodes
and false measurements due to air bubbles.

Mounting direction and flow measuring:
The flow value displayed by the transmitter is positive whatever the mounting direction of
the device, but the totalizer increases or decreases depending on several parameters,i.e.:
●8045 with a PVDF sensor:
The totalizer increases when the arrow on the side of the housing indicates the
flow direction, the lug shows the upstream direction and the marked coax cable
is connected according to fig. 3.3 or 3.4.
●8045 with a stainless steel sensor:
The totalizer increases when the arrow on the side of the housing indicates the
flow direction, the cable glands show the downstream direction and the marked
coax cable is connected according to fig. 3.3 or 3.4.
The minimum straight upstream (10 x DN) and downstream (3 x DN) distances must be
observed.
Please ensure that the pipe design does not allow the build up of air
bubbles or cavities within the medium as this will cause measuring
errors.

3.2 INSTALLATION
The 8045 flow transmitter can be installed into pipes using our specially designed fitting
system S020. DEUTSCH
The fitting 4must be installed into the pipe according to the installation specifications
within section 3.1.
●Insert the plastic nut 3onto the fitting 4 and snap the plastic ring 2into the
guide-bush 5.
●Insert the sensor into the fitting ensuring the arrow on the side of the housing
indicates the flow direction, and:
Version with a PVDF sensor: ensuring the sensor is sitting correctly, making
sure that the lug 6 is aligned correctly onto the fitting.
Version with a stainless steel sensor: ensuring the cable glands show the
downstream direction and the alignment of the electrodes is perpendicular to
the flow direction.
If the mounting is correct, the sensor housing 1cannot be rotated.
The plastic nut must only be tightened by hand!

3.3 GENERAL ELECTRICAL CONNECTION
●Use cables with a temperature limit of 80°C minimum.
●For normal operating conditions the measuring signal can be transmitted by a
shielded cable of 0.75 mm2 cross section.
●The line must not be installed in combination with carrying lines with a higher
voltage or frequency.
●If a combined installation cannot be avoided, a minimum space of 30 cm (1 ft)
should be respected.
●The cable diameter must be between 6 and 12 mm;
If 2 cables are needed, use the supplied multiway seal and 4-mm diameter cables.
●The power supply must be filtered and regulated - section 6.1
●Ensure the equipotentiality of the installation (power supply - transmitter - fluid):
- The various earth spots in the installation have to be connected together to
eliminate the potential differences that may occur between different earthes.
- Observe faultless grounding of the shield at both ends of teh cable.
- Earth the negative terminal of the power supply to suppress the common
mode currents. If direct earthing is not possible insert a 100 nF-condensator
between the negative terminal and the earth.
Special attention has to be paid if the transmitter is installed on plastic pipes
because there is no direct earthing possible.
Proper earthing is performed by earthing together the metallic devices such as
pumps or valves, that are as close as possible to the magmeter. If no such devices
are present, insert metallic piping parts (earthing rings, not supplied) into the
plastic pipes before and after the magmeter and earth them together. The earthing
rings shown in the diagram below must be in contact with the fluid.
Metallic devices (valve, pump, etc)
For plastic pipe applications
(*) or metallic parts, not supplied, inserted inside the pipe.
(**) If direct earthing is impossible, connect a 100 nF-condensator between the negative terminal and the
earth.
Shielding
Inside of the housing: Connect the shielding to the earth.
Take care not to completely untighten the screw. Insert shielding.

Relay: 3A max. fuse and circuit breaker (depending on
application).
●Do not apply both a dangerous voltage and a very low safety
voltage to the relays.
3.4 ELECTRICAL WIRING FOR THE 8045 FLOW TRANSMITTER
3.4.1 18-36 VDC without relays
Lift the transparent lid after having unfastened the screw. Remove the cover via the
screws on the front display and pull the cable through the cable glands and wire
according to one of the pin assignment diagrams below.
The electronics within the 8045 allows a PLC with a sourcing or sinking 4-20 mA entry to
be connected. Position A (Fig 3.3) provides a sourcing configuration and Position B
(Fig 3.4) a sinking configuration.
Seal the unused cable gland using the supplied obstructor to ensure the
tightness of the transmitter. Unscrew the cable gland nut, insert the
obstructor and screw the nut back on the cable gland.
