Coriolis Mass Flow Meter Working Principle and Operation using Animation
Coriolis Mass Flow Meter is a Direct type Flow Measurement instrument and Measures the Mass Flow. When there is no flow through the tubes then the tubes vibrate at a resonant frequency. When there is a flow through the tubes then depends on the flow & its mass the tubes vibration will change. The change in vibration is measured and it is proportional to Mass Flow.
Here, In our animation the red & blue colours on left & right side of tubes shown are sensors for measuring the vibration i.e. frequency. The tubes are vibrates at a resonant frequency. When there is no flow through the tubes then the vibration measured at both red & blue color sensors are same and the difference of frequency is Zero i.e. at no flow conditions. When there is a flow through the tubes then the tubes vibration will change depending on the amount of mass flow through the tubes. If mass flow is more then vibration will be more and vice versa. The vibration is measured at red and blue color sensors and their difference in signal is proportional to Mass Flow.
