Restricted upper range value is dependent on Mach number
For liquids, the occurrence of cavitation may also restrict the upper range value.
Operable flow range
The value, which is typically up to 49: 1, may vary depending on the operating conditions
(ratio between upper range value and lower range value)

Input signal
Integrated pressure and temperature measurement
The measuring device can also directly record external variables for density and energy
compensation.
• Measurement of pressure, temperature and flow in a true 2-wire version
This product version offers the following benefits:
• Recording of pressure and temperature at the same point, thus ensuring maximum accuracy
of density and energy compensation
• Easy testing of pressure measurement accuracy:
• Application of pressure by pressure calibration unit, followed by input into measuring device
• Automatic error correction performed by device in the event of a deviation
• Availability of calculated line pressure.
