When selecting the supply and discharge conduits,
please observe their resistance against the
Caution
temperature and pressure occurring in your
application.
For the best possible accuracy of the measured
value, keep the flow of sample water as constant as
Note
possible.
To keep the system short and prevent drops in
pressure, the connection lines to the measuring cell
Note
or the measuring module should be kept as short as
possible.
