5.1 Installation conditions
When installing the sensor, the system must be de-pressurized and the pipe in which
the sensor is to be installed must be empty.
For flow and temperature measurement, the inserted probe must always be completely
enclosed by the medium. If the sensor is used for empty pipe detection, the sensor
detects whether there is medium at the sensor tip and can thereby detect an empty
pipe.
The minimum insertion depth
3
of ≥ 12 mm must be adhered to.
The cutting ring of the process connection adapter
1
must be ≥ 25 mm away from the
probe tip
2
to avoid damage to the sensor element.
The sensor probe should be positioned in the middle of the pipe and must not be in
contact with the pipe wall.
A minimum distance of ≥ 10 mm from the tip of the probe to the pipe wall must be
maintained
4
.
For medium temperatures above 100 °C, the distance between the bottom of the
housing and the top of the process connection adapter must be at least 25 mm
5
.
NOTE:
If a Sick process connection adapter is used (see “14 Accessories”) , the 60 mm probe
cannot be used at process temperatures above 100 °C as the distances cannot be
maintained.

Distance between the cutting ring threaded connection and probe tip ≥ 25 mm

Distance from the probe tip to pipe wall ≥ 10 mm

Distance between the bottom of the housing and the top of the process connection
adapter at temperatures above 100 °C: ≥ 25 mm
The inlet zone before the sensor should be at least 5 to 10 times the pipe diameter.
The outlet zone after the sensor should be at least 3 to 5 times the pipe diameter.
