How Coriolis Mass Flow Meters Work
Digital Coriolis mass flow meters for liquids incorporate a vibrating tube through which the liquid passes. When the liquid flow passes through the tube, it induces a phase shift in the tube’s oscillation. This phase shift is directly proportional to the mass flow rate of the liquid. Advanced digital signal processing technology computes various parameters such as mass flow, density, and temperature, providing a complete profile of the fluid characteristics.
Steps of Operation
- Vibration Initiation: The meter’s tube is oscillated at a stable frequency.
- Fluid Induction: Liquid enters the vibrating tube.
