Turn-off devices for the zero point adjustment
1 Turn-off device
Figure 9: Mounting options for turn-off devices (example)
To guarantee the conditions for zero point balancing under
operating conditions, turn-off devices are required in the piping:
A At least on the outlet side when the transmitter is
mounted in horizontal position
B At least on the inlet side when the transmitter is mounted
in vertical position.
C In order to perform balancing during an ongoing process,
it is advisable to mount a bypass pipe.

medium
−50°to 205 °C (−58 to 400 °F)
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 10.
Heat tracing of the sensor
When operating the sensor in conjunction with heat tracing, the
temperature at point
C (Figure 10) 100 °C (212 °F) may not be
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 30.
• 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.
