Operable flow range
Over 1000 : 1.
Flow rates above the preset full scale value do not override the electronics unit, with the result that
the totalizer values are registered correctly.

External measured values
To increase the accuracy of certain measured variables, the automation system can continuously
write various 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)
Various pressure transmitters and temperature measuring devices can be ordered from Endress
+Hauser: see "Accessories" section →  109
HART protocol
The measured values are written from the automation system to the measuring device via the HART
protocol. The pressure transmitter must support the following protocol-specific functions:
• HART protocol
• Burst mode
Current input
The measured values are written from the automation system to the measuring device via the
