I suppose that both tubes are brought in resonancy by the same oscillator.

The pair is made to exclude the external vibrations from the receiver. Since both tubes are vibrating oppositely, external factors are canceled out this way. The phase shift is detected by two hall-principle sensors for every tube, depending on the manufacturer. Please let me know if you stumble upon extra information.

Alright, so let me recapitulate: The tube is moving up and down due to the external oscillator. When the angle of the tube is positive, relative to its starting position, the medium puts a downward force on the tube due to inertia on the incoming side, an upward force on the outgoing side. Because of the oscillator, the forces switch direction twice a period.

Hi Studiot, Is it possible to explain the "external oscillation dive"? I already watched the videos of all manufacturers, but like this one, all explain the consequence and not the cause of the bending. This makes sense to me, thanks for the explanation. I think I've found a graph that describes what you've explained.

Hi Guys, I am diving into the working principle of a Coriolis mass flow meter. I do understand how the mass flow is calculated and how the Coriolis principle works in theory based on rotating systems. The problem I encounter is that I can't match the theory with the practical application. The theory describes the force on an object in a rotating system that makes its path bend. But what is the initial cause for the bending of the tubing in the image underneath? (green arrow force) Is it the medium that shifts direction into the tube? Thanks
