The corilis mass flow meter basically detects the twisting
of an oscillationg ( vibration ) flow tube where the amount
of twist is a function of the mass flow through the tube.
The displacememnts or twisting motion are measured by
means of optical transducers whose outputs are a pulse a
with proportional to the mass flow rate

If there is no flow then no coriolis effect, if there is a flow then it will make coriolis effect. In coriolis flow meter, consists of two parellel flow tubes connected with a drive coil and two magnetic pick ups on either side of the tubes. During no flow condition, the drive coil makes a small vibratio in the tubes one another. Due to this vibration the magnetic pickoff coil will generate a voltage equilant to a sine wave. In this condition sine wave created by both the inlet and outlet magnetic pick up is same.
During in flow condition, then there is a twisting in the flow tube. In the inlet side the flow opposes the vibration and in the outlet side the flow adds the vibration and makes twistinh in the flow tube. Due to this twisting the pickoff coil makes different sine wave output. By measuring the phase shift with reference time will be calculated as t in micro seconds. Multiply t with the calibration factor, we will get the mass flow in grams/sec.

Answer / niraj sherathia / krupesh pate
A mass flow meter, also known as an inertial flow meter is
a device that measures mass flow rate of a fluid traveling
through a tube. The mass flow rate is the mass of the fluid
traveling past a fixed point per unit time.

Answer / pravesh ahlawat
This meter uses the Coriolis effect to measure the amount of mass moving through the element. The substance to be measured runs through a U-shaped tube that is caused to vibrate in a perpendicular direction to the flow. Fluid forces running through the tube interact with the vibration, causing it to twist. The greater the angle of the twist, the greater the flow
