Working Principle of the Coriolis Mass Flow Meters

Based on the Coriolis principle, the flow meter measures mass flow by detecting changes in the vibration frequency, phase difference, and amplitude of the measuring tubes. Fluid density is determined by measuring the tubes' resonant frequency. A built-in precision temperature sensor directly measures medium temperature and provides temperature compensation for flow and density measurements, enabling accurate multi-parameter measurement.
