4.4.6 Connecting the sample water inlet
Please note
Do not install water carrying lines made of copper. These would
distort the measurements.
When connecting the sample water inlet, observe the following:
• Sample water inlets are classified according to whether they
have a hose connection or are fitted with rigid piping.
• The pressure in the sample water inlet must always be within a
range of 0.25 to 3.0 bar. The pressure in the sample water
inlet must generally be 0.25 bar higher than in the sample
water outlet.
• At an admission pressure below 0.25 bar, an optional pressure
booster pump must be used. See chapter 4.4.7 – “Example for
sample water take-off with a booster pump”.
• If the admission pressure exceeds 3.0 bar, an optional pres-
sure reducing valve must be used. See chapter 4.4.7 – “Exam-
ple for sample water take-off”.
• To prevent long loop lag times, ensure that the lines in the
sample water inlet are as short as possible.
• An external strainer with a mesh width of 0.5 mm is provided
for the sample water inlet.
