13. How does it work?
Drive coil causes tubes to vibrate at natural frequency.
Electronics provide energy to drive coil, accept signals from pick-off coils, and output values for mass, volume, density, and temperature.
MICRO
MOTION
Pick-off coils generate sign waves used to indicate position of tubes to each other.

35. Why use a Coriolis meter?
Multi-Variable Measurement
Mass, Density, and Volume
Non-Intrusive - reduced maintenance
No moving parts - no mechanical parts to wear
Measures fluids laden with solids (ie sand)
Not damaged by slugs of air
Simple, Compact Installation
No straight pipe runs required
Accuracy
High turndown ratio
Reduced drift in accuracy due to wear
