5.5 Connecting the measuring
lines
In following, pressurized lines are designat -
ed " measuring lines ".
Risk of malfunction and incorrect measure-
ments due to mixing up the measuring
lines.
Î
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.
Î
Screw fittings are required to connect the
measuring lines (see 3/4 in Fig. 5-6 as
well as accessories in Annex B).
Î
Depending on the device arrangement,
seal the device connections that are left
unused with screw plugs (see 5 in
