2 Installation
2.1 Arrangement of instruments
2.2 Media 6 Indicating Unit
Make sure that the high-pressure line is
connected to the high-pressure connec-
tion and the low-pressure line to the low-
pressure connection.
Note!
Special fittings are required to connect
measuring lines. In addition, depending on
the arrangement, connections left unused
must be fitted with plugs or venting screws
(see section 2.5 on accessories for more de-
tails).
Clean the connections carefully prior to
connecting the measuring lines. Do not
clean the instrument using compressed
air or pressurized water.
Secure the instrument at the place of in-
stallation to a pipe, wall or mounting
plate
free of vibration
.
For attachment to vertical or horizontal
pipes, use a mounting component with
clamp. For wall mounting, use a mount-
ing part without clamp. See the dimen-
sional drawing on page 29 for mounting
to control panels.
Note!
We recommend installing one shut-off valve
in each measuring line and, additionally,
an equalizing valve, or a SAMSON valve
block as a compact assembly.
Both measuring lines can then be shut off.
Additionally, the zero point can be checked
at the indicating unit by bypassing the
circuit.
2.3 Valve block
The three valves combined in a valve block
with test and pressure gauge connections
(Fig. 4), which are flanged directly onto the
bottom of the dp cell, are available as an
accessory.
2.4 Shut-off and equalizing valves
As an alternative to the SAMSON valve
block, both shut-off valves as well as the by-
pass valve/equalizing valve can also be in-
stalled as shown in Fig. 5.
