What type of flow meter depends upon the twist of the tube containing the flowing fluid to sense flow rate?

Explanation:
The effect being used is the Coriolis effect on fluid inside vibrating tubes. In a Coriolis flow meter, the tubes are made to vibrate, and as fluid flows through them the inertia of the moving fluid causes a twist or torsion in the tubes. The amount of twist (or the phase difference between the tube ends) is proportional to the mass flow rate. Sensors read this twist and convert it into a flow rate reading, giving direct mass flow measurement. This twisting signal is unique to Coriolis devices, unlike ultrasonic meters (sound waves) or vortex meters (vortex shedding), and unlike a generic “mass” meter, which isn’t a specific measurement principle by itself.
