External measured values
To increase the accuracy of certain measured variables or to calculate the corrected volume
flow for gases, the automation system can continuously write different measured values to
the measuring device:
• Operating pressure to increase accuracy (Endress+Hauser recommends the use of a
pressure measuring device for absolute pressure, e.g. Cerabar M or Cerabar S)
• Medium temperature to increase accuracy (e.g. iTEMP)
• Reference density for calculating the corrected volume flow for gases
Various pressure transmitters and temperature measuring devices can be ordered
from Endress+Hauser: see "Accessories" section →  106
It is recommended to read in external measured values to calculate the following measured
variables:
• Mass flow
• Corrected volume flow
Digital communication
The measured values are written from the automation system to the measuring device via
PROFIBUS DP.
