3.1 Mounting
Mounting and setup must be carried out according to the applicable installation standards
(e.g. EN 60079-14) by qualified personnel trained in explosion protection. The information given
in the manuals and the supplementary instructions must be observed at all times.
Variable area flowmeters must be installed in such a way that
•
there is no danger from mechanical impact effects.
•
no external forces are affecting the indication unit.
•
the device is accessible for any necessary visual inspections and can be viewed from all sides.
•
the nameplate is clearly visible.
•
it can be operated from a location with secure footing.
3.2 Special conditions
Electrostatics
For painted versions, risks due to electrostatic charge must be minimized.
Observe additional information regarding electrostatics. For further information refer to
Electrostatic charge
on page 18.
Wetted parts made of titanium
When dealing with device versions of the type series H250 with wetted parts made of titanium (TI
option), use the protected installation to prevent sparking due to external impact and friction
between titanium and other materials.
Thermal and electrical data
Observe the maximum ambient and product temperatures and electrical data. For further
information refer to
Ambient temperature / temperature classes / product temperature
on page
11 and refer to
Surface temperature for equipment category II 2 D
on page 13 and refer to
Electrical data
on page 13.
CAUTION!
The manufacturer is not liable for any damage resulting from improper use or use other than the
intended purpose. This applies in particular to hazards due to insufficient corrosion resistance
and suitability of the materials in contact with product.
