1.1 General notes
These additional instructions apply to intrinsically safe versions of vortex flowmeters with
following specifications:
•ATEX category: II 1 G and II 2 D
•Equipment protection level (EPL): Ga and Db
•Ex marking: Ex ia IIC T4 Ga and Ex tb IIIC T103°C Db
They complete the standard documentation for the non-explosion protected versions.
The information given in this instruction contains only the data relevant to explosion protection.
The technical details given in the manual for the non-explosion protected versions remain
unchanged unless they will be excluded or replaced by this instruction.
1.2 EU conformity
The manufacturer declares with the EU declaration of conformity on his own responsibility
conformity with the protection goals of directive 2014/34/EU for use in hazardous areas with gas
and dust.
Conformity with harmonised standards was checked by a notified body in accordance with
EN 60079-0:2012, EN 60079-1:2014, EN 60079-11:2012, EN 60079-26:2007 and
EN 60079-31:2014.
The EU declaration of conformity for the equipment categories is based on the EU type
examination certificate:
The "X" after the certificate number refers to special conditions for safe use of the device, which
have been listed in these instructions.
If needed the EU type examination certificate can be downloaded from the manufacturer's
website.

1.3 Approval according to the IECEx scheme
Conformity of the vortex flowmeter for use in hazardous areas with gas and dust was tested in
accordance with the "IECEx Certification Scheme for Explosive Atmospheres" according to
IEC 60079-0:2011, IEC 60079-1:2014, IEC 60079-11:2011, IEC 60079-26:2004 and
IEC 60079-31:2013. The number of the IEC certificate is:
The "X" after the certificate number refers to special conditions for safe use of the device, which
have been listed in these instructions.
If needed, the IEC certificate can be downloaded from the manufacturer's website.
1.4 Safety instructions

2.1 Device description
Vortex flowmeters measure and display the flow of flammable and non-flammable gases, steam
and liquids. They transmit a 4...20 mA or digital multidrop, and a pulse output signal, as
applicable, using HART
®
communication protocol for remote configuration, calibration and
monitoring.
2.2 Marking
The marking of the devices is shown on the nameplate below. On both the compact devices and
the remote versions, the main plate is located on the signal converter housing. When the
flowmeter is remotely mounted, the junction box on the flow sensor has an nameplate showing
its hazardous location rating.
Compact devices with two signal converters for dual measurement (Dual Version) are each
marked with a nameplate. The details relevant to explosion protection are identical on both
nameplates.
