Coriolis Mass Flow Meter

Working Pricipciple : 

• The basic operation of Coriolis mass flow meters is based on the principles of motion mechanics.
• Coriolis Mass Flow meter  contains a vibrating tube in which a fluid flow causes,  changes in frequency, phase shift or amplitude.
• The sensor signal is fed into the integrally mounted pc-board.
• The resulting output signal is strictly proportional to the real mass flow rate, whereas thermal mass flow meters are dependent of the physical properties of the fluid.
• Coriolis mass flow measurement is fast and very accurate.

Importance

• The  Coriolis meter  principle is based on  motion mechanics.
• As the process fluid enters the sensor, it gets splitted.

Coriolis Mass Flow Meter

• During operation, a drive coil stimulates the tubes to oscillate in opposition at the natural resonant frequency.
• As the tubes oscillate, the voltage generated from each pickoff creates a sine wave.
• This indicates the motion of one tube relative to the other.
• The time delay between the two sine waves is called Delta-T, which is directly proportional to the mass flow rate.
