Installation
3.1
Arrangement of
instruments for liquid level
measurement
In arrangements as illustrated in the second
schematic drawing, the additional height z is
included in the measurement. As a result,
this height must be as low as possible.
The dimension K (compensation height, see
Fig. 2) can be as large as required by the
conditions in the plant.
3.2
Arrangement of devices for
flow rate measurement
The decision whether the meter is to be
mounted above or below the measuring
point or whether compensation chambers
are required depends on the process medi-
um and the specific conditions in the plant.
The installation drawing shows standard and
reverse installation. Standard installation is
preferable in any case.
Reverse installation can only be used when
there is no other possibility, particularly for
steam measurements.
Refer to VDE/VDI 3512 Sheet 1 for details.
3.3
Media 05 indicating unit
Make sure that the high-pressure line is con-
nected to the high-pressure connection and
the low-pressure line to the low-pressure con-
nection.
Special screw fittings are required to connect
the differential pressure lines. Depending on
the device arrangement, seal any connec-
tions left unused with stoppers or vent plugs
(see section 4.4).
Carefully clean the connections before at-
taching the differential pressure lines.
Do not rinse the device with compressed air
or pressurized water.
Mount the device to a pipe, wall or mounting
plate free of vibration.
Use mounting part with clamp for pipe
mounting to attach it to a vertical or horizon-
tal pipe. Use a mounting part without clamp
for wall mounting.
A mounting bracket is required for panel
mounting (see section 8).
