Installing the device connections
The connection lines are categorized as follows:
▪
Measuring impulse lines
The pressure of a gas is found inside measuring impulse lines. Gas does not flow
through these lines.
▪
Operating lines
A gas flows through operating lines. The specific operating lines are as
follows:
▪
Vent lines
▪
Blowdown lines
▪
Bleed lines
▪
Return lines
Some of the measuring impulse lines will come pre-installed:

Prepare the following materials:
▪
Pipes, connecting pieces, and fittings as per the specifications in the
Technical specifica-
tions
(see page 22)
▪
Shut-off devices for the operating and measuring impulse lines, as well as other acces-
sories as required.
The installation of the operating and measuring impulse lines depends on the local conditions
and the gas regulating line in which the gas pressure regulator is being used. Please refer to
the
Basics for installing the device in a pipe
(see page 36) section for more information on
what needs to be ensured without fail in the corresponding design and implementation.
