Safety

1.10 Technical limit values

The device is designed for use exclusively within the stated values on the name plate and within
the technical limit values specified in the data sheets.
The following technical limit values must be observed:
• The permissible operating pressure (PS) in the permissible temperature (TS) may not
exceed the pressure-temperature ratings.
• The maximum operating temperature may not be exceeded.
• The permitted operating temperature may not be exceeded.
• The housing protection system must be observed.
• The flowmeter sensor may not be operated in the vicinity of powerful electromagnetic fields,
e.g., motors, pumps, transformers, etc. A minimum spacing of approx. 1 m (3.28 ft) should
be maintained. For installation on or to steel parts (e.g., steel brackets), a minimum spacing
of approx. 100 mm (3.94 inch) should be maintained (based on IEC801-2 and IECTC77B).

1.11 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
into contact with the fluids (signal electrodes, ground electrodes, liners and, possibly,
process connections, protective plates or protective flanges) are not affected during the
operating life.
Fluids with unknown properties or abrasive fluids 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.

1.12 Maintenance and inspection safety information

Warning – Risk to persons!
When the housing cover is open, EMC and protection against contact are suspended. There
are electric circuits within the housing which pose a contact risk.
The auxiliary power must be switched off before opening the housing cover.
Warning – Risk to persons!
The inspection screw (for draining condensate fluid) for devices ≥ DN 350 can be under
pressure. The medium which spurts out can cause severe injuries.
Depressurize pipes before opening the inspection screw.
Corrective maintenance work may only be performed by trained personnel.
• Depressurize the device and adjoining lines or containers before removing the device.
• Check whether hazardous materials are used as materials to be measured before opening
the device. Residual amounts of hazardous material may still be present in the device and
could escape when the device is opened.
• As far as provided in the scope of the operational responsibility, check the following items
through a regular inspection:
 the pressure-carrying walls / lining of the pressure device
 the measurement-related function
 the leak tightness
 the wear (corrosion)
