The sensor may only be insulated in conjunction with the option
TE1 'Extended tower length for sensor insulation' or TE2
'Extended tower length – insulation capacity with dual gasket,'
as shown in Figure 13.

Heat tracing of the sensor

When operating the sensor in conjunction with heat tracing, the
temperature at point (Figure 13) 100 °C (212 °F) must not be
C
exceeded at any time!
Installation in EHEDG-compliant installations
WARNING
Risk of poisoning!
Bacteria and chemical substances can contaminate or pollute
pipeline systems and the materials they are made of.
• In EHEDG-compliant installations, the instructions below
must be observed.
• The required self-draining functionality of the sensor can
only be guaranteed when the vertical mounting position or
horizontal mounting position at a 30° incline is used. Refer to
Liquid measuring media on page 32.
• The combination of process connections and gaskets
selected by the operator may comprise only EHEDG-
compliant components. Please note the information in the
latest version of the EHEDG Position Paper: 'Hygienic Process
connections to use with hygienic components and
equipment' in this regard.
• The pipe fitting in accordance with DIN 11851 is approved for
use in conjunction with an EHEDG-compliant gasket.

Devices for legal metrology in accordance
with MID / OIML R117
The Coriolis mass flowmeters CoriolisMaster FCBx50 / FCHx50
are type-tested for legal metrology in accordance with
MID / OIML R117 in accuracy class 0.3.
Additional information can be found on the corresponding
certificate. The certificate is available in the download area at
www.abb.com/flow.

Figure 14: Sealing in accordance with MID / OIML R117 (example)
On devices for legal metrology in accordance with
MID / OIML R117, the hardware write protection must be
activated after commissioning.
This prevents a change in the parameterization of the devices.
Hardware settings on page 64
To prevent deactivation of the hardware write protection or
other manipulations during operation, the transmitter housing
and the sensor housing connection box (with remote mount
design) must be sealed.
For this purpose, a seal kit is available at ABB.
For the assembly of the seal, please observe the separate
'IN/FCX100/FCX400/MID/OIML-XA' instructions.
