• The housing protection system must be observed.
1.5

Allowed Fluids

When measuring fluids, the following points must be observed:
• Fluids may only be used if, based on state-of-the-art technology or the operating experience
of the user, it is assured that chemical and physical properties of the components coming

process connections, protective plates or protective flanges) are not affected during the
operating life.
Fluids with unknown properties or abrasive agents may only be used if the operator can
•
perform regular and suitable tests to ensure the safe condition of the device.
• Observe the information on the name plate.
1.6

Operator liability

Before the use of corrosive and abrasive measuring medium, the operator must clarify the
