Input
Measured variable
• Mass flow
(proportional to the phase difference between two sensors mounted on the measuring tube which
register a phase shift in the oscillation)
• Fluid density
(proportional to the resonance frequency of the measuring tube)
• Fluid temperature
(via temperature sensors)/(not suitable for custody transfer measurement)
