2 Installation
2.1 Arrangement of devices for
liquid level measurement
Schematic drawings 1 to 3 (see Fig. 2)
In arrangements as illustrated by schematic
drawing 2, the additional height z influences
the measurement. As a result, the height must
be as low as possible.
No restrictions apply to dimension K (com-
pensation height) illustrated in schematic
drawing 3; it can be as high as required by
the conditions in the plant.
2.2 Arrangement of devices for
flow rate measurement
The decision whether the meter is to be
mounted above or below the measuring point
or whether equalizing tanks are required de-
pends on the type of process medium and the
specific conditions in the plant. The installa-
tion drawing shows standard and reverse in-
stallation. Standard installation is preferable
in any case. Reverse installation can be used
only when there is no other possibility, partic-
ularly for steam measurements. Refer to
VDE/VDI 3512 Sheet 1 for details.

2.3 Media 6 indicating unit

Make sure that the high-pressure line is con-
nected to the high-pressure connection and
that the low-pressure line is attached to the
low-pressure connection.
Special fittings are required to connect the
differential pressure lines. Depending on the
device arrangement, seal any connections left
unused with plugs or vent plugs.

Carefully clean the connections before attach-
ing the differential pressure lines. Never flush
the device with compressed air or pressurized
water!
At the place of installation, mount the meter to
a pipe, wall or mounting plate, ensuring that it
is free of vibration.
Use the fastening element with clamp for
mounting to vertical or horizontal pipes. For
wall mounting, use the fastening element with-
out clamp. A mounting bracket (see dimen-
sional drawing on page 32) is required for
panel mounting.

2.4 Differential pressure lines

Install the differential pressure lines (pipes with
12 mm outside Ø) as illustrated in Fig. 3. Ob-
serve the proper arrangement! Use appropri-
ate screw fittings to ensure that the lines do not
leak.
Install line sections, which would usually run
horizontally, with a constant downward slope
of at least 1:20, starting the slope either at the
orifice plate or at the point where venting is
possible. The smallest permissible bending ra-
dius is 50 mm.
Thoroughly flush the differential pressure lines
before connecting them to the device. Make
sure that the high-pressure line is connected to
the high-pressure connection and that the
low-pressure line is attached to the low-pres-
sure connection.
