• The measuring device complies with the general safety requirements in accordance with
EN 61010, the EMC requirements of EN 61326/A1, and NAMUR recommendation NE 21.
• The manufacturer reserves the right to modify technical data without prior notice. Your
Hauser distributor will supply you with current information and updates to these
Operating Instructions.
1.4 Return
The following procedures must be carried out before a flowmeter requiring repair or calibration,
for example, is returned to Hauser:
• Always enclose a duly completed “Declaration of contamination” form. Only then can
Hauser transport, examine and repair a returned device.
• Enclose special handling instructions if necessary, for example a safety data sheet as per
EN 91/155/EEC.
• Remove all residues. Pay special attention to the grooves for seals and crevices which could
contain residues. This is particularly important if the substance is hazardous to health, e.g.
flammable, toxic, caustic, carcinogenic, etc.
!
Note!
You will find a
preprinted “Declaration of contamination” form at the back of this manual.

if you are not absolutely certain that all traces of hazardous
substances have been removed, e.g. substances which have penetrated crevices or diffused
through plastic.

charged to the owner-operator.
