Recommended measuring range
"Flow limit" section →  139
Operable flow range • 30 : 1 (standard; order code for "Calibration Flow", option 1 "Operable flow range 30 : 1")
• 100 : 1 (optional; order code for "Calibration Flow", option 2 "Operable flow range 100 :
1")
Flow rates above the preset full scale value do not overload the amplifier so the totalized
values are registered correctly.
Input signal Current input
Current input 4-20 mA (passive)
Resolution 1 µA
Voltage drop Typically: 2.2 to 3 V for 3.6 to 22 mA
Maximum voltage ≤35 V
Possible input variables Pressure
External measured values
To increase the accuracy of certain measured variables, the automation system can
continuously write the operating pressure to the measuring device. Endress+Hauser
recommends the use of a pressure measuring device for absolute pressure, e.g. Cerabar M
or Cerabar S
Various pressure transmitters can be ordered from Endress+Hauser: see "Accessories"
section →  129
It is recommended to read in external measured values to calculate the following measured
variables:
• Energy flow
• Mass flow
• Corrected volume flow
• Corrected methane volume flow
