Connecting the sample water
outlet
4.9.1 Non-pressurized version
When connecting the sample water outlet,
observe the following:
•
Do not install water carrying lines made of
copper. These would falsify the measure-
ments.
•
On the non-pressurized version, no back-
pressure is permitted in the cell body
(design chapter 4.8 - Fig. 3).
•
The sample water outlet must be open.
We recommend using a funnel above the
outlet.
•
The sample water outlet must be laid in
such a way as to prevent siphoning.
4.9.2 Pressurized version
When connecting the sample water outlet,
observe the following:
•
Do not install water carrying lines made of
copper. These would falsify the measure-
ments.
•
Ensure that the drain screw (sample
taking unit) is always closed.
•
On the pressurized version, a maximum
back-pressure of 1.5 bar is permitted on
the sample water outlet.
NOTICE
The water-tightness of the hose screw con-
nection is only guaranteed if the following
installation instructions are followed!
NOTICE
Ensure that the sample water pipes are
installed free of mechanical stress.
