safe apparatus according to standards IEC 60079-0:2007, IEC 60079-11:2007 and IEC
60079-26:2006.
According to the ATEX directive (94/9/EC) our EX flow monitors are considered as "simp-
le apparatuses" according to EN 60079-11:2006. The monitors contain mechanical parts
that move slowly and with low power input, incapable of forming hot surfaces or other
ignition sources even in cases of rare malfunction. The ATEX directive is not applicable
for "simple apparatuses" or for slow moving mechanical parts with low power input.
The monitors have been designed and examined as simple apparatus according to EN
60079-0:2009, EN 60079-11:2006, EN 60079-26: 2007 and EN 13463-1:2009.
Note! Installation and maintenance of Ex versions should be executed according to
applicable national laws and regulations. Within EU, directive 1999/92 EC should be
considered. EU members within CENELEC should consider the requirements within
national standards, based on EN-60079-14 and EN60079-17.
Specific for Ex versions
Each flow monitor approved for use in explosive environment is marked with a yellow
label that contains information of: The Explosion protection code, Certificate Id and the
Intrinsically safe parameters that apply for connection of the flow monitor.
The spacers inside of the FA and GL pipe sections are made in stainless steel.
Service/Installation/Replacement
The control unit may be delivered without a mounted pipe section, in case a unit needs
to be replaced. The type designation on the product label of the control unit then applies
for the complete assembled Flow monitor (control unit and pipe section). An Ex version
control unit should only be mounted with a pipe section in accordance to the information
on the product label.
To avoid a potential difference between pipe system and the flow monitor there are two
ring cable shoes supplied with our Ex products. The ring cable shoes may be attached
onto the diaphragm housing screws and used as ground terminals to ensure terminal
grounding between pipe section and the connecting pipe system.
Special conditions for safe use:
1 The blue enclosure and surfaces of the control unit are made of aluminum. This light
metal part shall not be subject to impacts or friction in order to avoid sparks.
2 The process connection to the Flow monitor must be performed to be sufficiently
sealed between the inside and outside of the process connection.
3 To avoid electrostatic charging of the enclosure the internal earth connection must
be connected to earth.
4 The temperature class must not be mixed up with the maximum working temperature.
The temperature class for the equipment depends on the ambient temperature. Note!
Ambient temperature must not exceed the maximum temperature of the medium.
