Operational safety
Note the following points:
• Measuring systems for use in hazardous environments are accompanied by separate
Ex documentation, which is an integral part of these Operating Instructions. Strict compliance
with the installation instructions and ratings as stated in this supplementary documentation is
mandatory. The symbol on the front of this documentation indicates the approval and the
inspection authority (e.g.
0
Europe,
2
USA,
1
Canada).
• The measuring device complies with the general safety requirements in accordance with
EN 61010-1, the EMC requirements of IEC/EN 61326, and NAMUR recommendation NE 21
and NE 43.
• Due to the performance rate in the electronic components, the maximum heating of the outer
housing surfaces is 10 K. When hot fluids are passed through the measuring tube, the surface
temperature of the housing increases. With regard to the sensor, in particular, you should expect
temperatures that can be close to the fluid temperature.
If the temperature of the fluid is high, ensure staff are protected against burns and scalds.
• 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.

Return
• Do not return a measuring device 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.
• Costs incurred for waste disposal and injury (burns, etc.) due to inadequate cleaning will be
charged to the owner-operator.
