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
Correct
When mounting vertically ensure that theflow direction is in an upward
direction as indicated by the arrow.
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.
