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.
