3 Installation
3.1 Installation of the assembly
The flow assembly should only be installed in
pipes at locations where the pipe cannot run
dry. Installation in the by-pass is preferable to
installation in the process pipe as the by-pass
pipe can be blocked off without interrupting
the process. This permits measurement,
sampling and maintenance of the electrode
without interrupting the process.
The drain screw fitted to the flow assembly
base permits the connection of outlet or
sampling pipes.
Warning:
•Depressurise the pipe before
installing or removing the
assembly.
•The medium pressure in the pipe
must not exceed the maximum
permissible flow assembly or
electrode pressure.
