10 Technical data
10.1 Technical data at a glance
10.1.1 Applications
The measuring device is for mass flow and volume flow measurement of liquids and
gases in sealed piping systems. Application examples:
• additives
• oils, fats
• acids, alkalis
• lacquers, paints
• suspensions
• gases.
10.1.2 Function and system design
Measuring principle Mass flow measurement by the Coriolis principle
Measuring system The measuring system consists of a transmitter and a sensor:
• Promass 40 transmitter
• Promass E sensor
10.1.3 Input
Measured variable • Mass flow (proportional to the phase difference between two sensors mounted on the
measuring tube to register a phase shift in the oscillation)
• Volume flow (calculated from mass flow and fluid density, which is proportional to the
resonance frequency of the measuring tubes)
• Fluid temperature (registered by temperature sensors) for compensating temperature
effects.
