Upper range value
Liquids:
The upper range value must be calculated as follows:
v
max
= 9 m/s (30 ft/s) and v
max
= 350/√ρ m/s (130/√ρ ft/s)
‣
Use the lower value.
Gas/steam:
Nominal diameter v
max
Standard device: DN 15 (½") 46 m/s (151 ft/s) and 350/√ρ m/s (130/√ρ ft/s)
(Use the lower value.)
Standard device: DN 25 (1"), DN 40 (1½") 75 m/s (246 ft/s) and 350/√ρ m/s (130/√ρ ft/s)
(Use the lower value.)
Standard device: DN 50 to 300 (2 to 12") 120 m/s (394 ft/s) and 350/√ρ m/s (130/√ρ ft/s)
(Use the lower value.)
Calibrated range: up to 75 m/s (246 ft/s)

Operable flow range Up to 45: 1 (ratio between lower and upper range value)
Input signal External measured values
To increase the accuracy of certain measured variables or to calculate the corrected volume
flow, 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
• Various pressure transmitters can be ordered from Endress+Hauser: see
"Accessories" section → 183
• Please comply with the special mounting instructions when using pressure
transmitters → 24
It is recommended to read in external measured values to calculate the following measured
variables:
• Energy flow
• Mass flow
• Corrected volume flow
Fieldbuses
The measured values are written from the automation system to the measuring device via
PROFIBUS PA.
