Mounting
Parameters are transferred with the IO-Link functions. The previously configured master sensor is set
to a master mode, which enables it to transfer its parameters to an identical device sensor.

Switchover of standard condition
The represented flow rate units and volume units can be related to different standard conditions. It is
possible to switch between the following standard conditions. In the menu navigation on the display,
the corresponding standard is determined by selecting the reference temperature.

Tab. 9: Standard conditions for flow rate units and volume units
Calibration of the sensor refers back to the physical standard conditions in accordance with DIN 1343.
If a standard other than DIN 1343 is selected, the specified measurement range (±100 % FS)changes
in value by the factor specified in
Tab. 9 Standard conditions for flow rate units and volume units.
This change is visualised in the display through ‘Option’.
Changing the reference standard only adjusts the display on the sensor. If necessary, the effect on the
nominal measurement range of the respective sensor must also be considered when evaluating the
analogue output.
4.2.10
Zero point synchronisation
If the sensor is installed vertically, the measurement may deviate at high pressures. An offset synchro-
nisation can be carried out to compensate for the measurement deviation. This offset synchronisation
affects the display and all outputs. The offset synchronisation is possible only for the Zero Adjust = ON
setting and the zero range hiding is no longer active. The offset error is visible on the display and can
be set to zero using a zero-adjust teach process.

Mounting
When selecting the mounting position, make sure that no condensation water can accumulate in the
sensor.
