Important Information
Subject to change without notice
1.3.2.5 Sender/receiver unit with probe retraction mechanism
The retraction mechanism serves to remove and fit complete FLOWSIC100 Flare sender/
receiver units for maintenance or replacement without relieving pressure in the pipeline in
which the measuring system is fitted. This allows maintenance work without having to
interrupt the process.
1.3.2.6 MCUP control unit
The MCUP control unit is optionally available in the versions for use in Ex zone 1 and 2 or
for use only in Ex zone 2 or not for use in Ex zones.
WARNING: Specified temperature and pressure ranges
Only operate probe retraction mechanism in the following ranges for gas
temperature and operating pressure:
● Device types FL100 EX-S, EX and EX-RE:
– Gas temperature range -20°C to +200 °C
– Upper operating pressure 16 bar at 50 °C (see p-T diagrams in chapter
2.3.1.1 - 2.3.1.6.)
● Device type FL100 EX-PR
– Gas temperature range -20°C to +200 °C
– Upper operating pressure limit is +0.5 bar at whole temperature range.
WARNING: Hazardous gas (possibly explosive or toxic)
Small gas quantities escape during the removal and installation of the
transducer assemblies. During proper use, the gas crowd locked up in the
retraction space is less than 0.5 dm³ for device type EX-S, EX and EX-RE and
less than 2.5 dm³ for device type EX-PR.
 Staff performing activities at plants with poisonous or other gases
dangerous to health must use suitable safety equipment to prevent
personal injuries.
WARNING: Hazardous gas (possibly explosive or toxic)
The retraction flange of the S/R units contains a connection for optional vent-
ing ( → Fig. 8, → Fig. 12 and → Fig. 16 - Fig. 22).
 This connection is closed with a blind screw by factory and may not be
removed outside factory!
● Control units with marking ATEX II 2 G Ex de II C T6 are approved for use in
Ex zone 1 and 2.
● Control units with marking ATEX II 3 G Ex nA IIC T4 Gc are approved for use
only in Ex zone 2 or for use in safe areas.
WARNING: Explosion hazard
 Install and operate the MCUP control unit without explosion protection only
outside Ex zones.
 Use the explosion-protected MCUP control unit only according to the
respective Ex marking.
