5.4.4 Connecting the sample water inlet
Please note
No water pipes made of copper may be fitted in the installation. They
would falsify the measurement.
When connecting the sample water inlet, note the following:
• A distinction must be made between a sample water inlet with tubing
connection and a sample water inlet with rigid pipework.
• The pressure in the sample water inlet must always be within a range
of min. 0.25 to max. 3.0 bar. The pressure in the sample water inlet
must always be 0.25 bar higher than in the sample water outlet.
• If the admission pressure is below 0.25 bar, a booster pump must be
used.
• If the admission pressure exceeds 3.0 bar, an optional pressure
reducing valve must be used.
• To prevent long loop lag times, ensure that the lines in the sample
water inlet are as short as possible.
• An optional strainer (W3T158721) with a mesh size of 0.5 mm can be
provided for the sample water inlet.
