lThe device must be protected against constant heat radiation and other
environmental influences such as magnetic fields or direct exposure to
sunlight.
lEnsure that the device is not located near any large machinery which
may interfere with the transmitter as this can have an effect on the
measurement readings.
In order to ensure a high precision of the measure and good stability of
the 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.

INSTALLATION
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
Correct Incorrect
Mounting vertically
Correct Incorrect
When mounting vertically ensure that the flow direction is in an upward
direction as indicated by the arrow.
45°

3.1.1
It is advisable to mount the transmitter at a 45°
angle to the horizontal centre of the pipe as
shown in the diagram.

8045
ENGLISH
INSTALLATION
The minimum upstream (10 x D) and downstream (3 x D) distances must be
observed.
Flow direction
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.
Flow direction
Flow direction
Correct Incorrect
Correct Incorrect
Measuring flow direction:
The measuring flow direction depends on the mounting direction of the transmitter. To
inverse the measure turn the transmitter 180° on the fitting for a positive flow direction
ensuring that the lug is in the upstream direction (see Fig. 3.1). The flow display is
always positive but the totalizers increase or decrease depending on the flow direction.

3.2 INSTALLATION
The 8045 flow transmitter can be easily installed into pipes using our specially
designed fitting system S020. DEUTSCH
The fitting 4 must be installed into the pipe according to the installation specifications
within section 3.1.
lInsert the plastic nut 3 onto the fitting 4 and snap the plastic ring 2 into the
guide -bush 5.
lEnsure that the sensor is fully inserted and sitting correctly, making sure that
the lug 6 is aligned correctly onto the fitting and that the sensor housing 1
cannot be rotated.
The plastic nut must only be tightened by hand!

INSTALLATION
3.3 GENERAL ELECTRICAL CONNECTION
lUse cables with a temperature limit of 80°C minimum.
lFor normal operating conditions the measuring signal can be transmitted by a
simple cable of 0.75 mm2 cross section.
lThe line must not be installed in combination with carrying lines with a higher
voltage or frequency.
lIf a combined installation cannot be avoided, a minimum space of 30 cm (1 ft)
or shielded cables should be adopted.
lWhen using shielded cables observe faultless grounding of the shield.
lIn case of doubt, always use shielded cables.
lThe power supply must be regulated - section 6.1
lDo not open and wire the transmitter with the power supply
connected.
lIt is advisable to put security devices on :
Power supply: Fuse (eg/ 250mA) and an interrupter
Relay: 3A fuse max. and circuit breaker (depending on application).
3.3.1 EARTHING THE TRANSMITTER
For EMC purposes and in order to ensure accurate measurement, it is
important that the transmitter is connected to the earth correctly as improper
earthing can have an adverse effect on the transmitter and flow measurement.
For correct earthing, the earth lug on the side of the enclosure must be
connected to a good local earthing point via an insulated cable of 2mm2 and
one of the diagrams below must be followed.
The earthing rings shown in the diagram below must be in contact with
the fluid and are not supplied by Bürkert.

Switch1: This switch allows a sinking or sourcing PLC to be connected (output
current). For further information see section 3.4.1.
Switch2 :lThis switch allows the Enter key to be locked to avoid accidental
or unauthorized access to the Programmation and Test menus.
lThe Switch2 when set in the unlocked position allows the
parameter values to be changed (K-Factor, relays, current, ...)
and when in the locked position access to the programmation and
test menus is restricted.
