Installation
3.1 Installation
Installation 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.
Vortex flowmeters must be installed in such a way that
• There are no external forces affecting the indicator part.
• The device is accessible for any visual inspections that are necessary, and can be viewed from
all sides.
• The nameplate is clearly visible.
• It can be operated from a location with secure footing.
Converter alignment
The converter may be aligned on the base in 90° increments up to a maximum of ± 180°.
For this reason, the four M6 hexagon socket screws connecting the base and the converter must
be loosened. Once the converter has been turned, it must be screwed back on to the base again
(tightening torque 6 Nm).
• De-energise the converter.
• Loosen the 4 hexagon socket screws.
• Turn the converter.
• Screw base to converter once again.
