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.

contain residues. This is particularly important if the substance is hazardous to health, e.g.
flammable, toxic, caustic, carcinogenic, etc.
