3.1 Mounting
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
• 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.
Aligning the signal converter
The signal converter and the connection box of remote systems may be aligned on the base up to
a maximum of ± 180 . For this reason, the M4 hexagon socket screw connecting the base, the
converter and connection box must be loosened. Once the signal converter and the connection
box has been turned, it must be screwed back on to the base again (tightening torque 2 Nm).
• De-energise the signal converter.
• Loosen the hexagon socket screw 1.
• Turn the signal converter or connection box.
• Screw signal converter or connection box back to the base again.
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.
