Product testing
DANGER!
Imprecise display in the event of deviations in system pressure!
If the system pressure of 500 kPa ± 10% is undercut or exceeded, it will no longer
be possible to accurately display the measured values of the flowmeter.
DANGER!
Fluctuations in flow rate!
Flow accuracy may be influenced by the following factors:
• Fluctuations in the supply pressure (terminal unit)
• Fluctuations in the back pressure (accessories)
• Fluctuations in the ambient temperature
DANGER!
Product testing!
Only product parts which are in perfect condition can ensure proper functioning of
the product. The product parts will thus have to be carefully inspected before
mounting.
WARNING!
Measurement accuracy!
The product may only be operated in a vertical position.
Pay special attention to the firm fit of the flowmeter viewing tube and to any possible cracks in
the flowmeter viewing tube. Do not use the product if there are any signs of cracks.
Check whether the connection tubes are undamaged.
Check whether the product has been properly cleaned and that there are no residues or
soiling.
