To guarantee the conditions for zero point balancing under
operating conditions, turn-off devices are required in the piping:
At least on the outlet side when the transmitter is
A
mounted in horizontal position
At least on the inlet side when the transmitter is mounted
B
in vertical position.
In order to perform balancing during an ongoing process,

Sensor insulation

1 Insulation
Figure 10: Installation at T
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
G11589
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.
