Measuring system
Measuring principle Coriolis mass flow
Application range Mass flow and density measurement of fluids, gases and solids
Measured values Mass, density, temperature
Calculated values Volume, referred density, concentration, velocity
Design
Basic System consists of a measuring sensor and a converter to process the
output signal
