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.

How does it work? Factory Calibration
How does it work? % of full scale flow Four Point Calibration % Error 25% 50% 100% Repeated % Error Four Point Calibration % of full scale flow
How does it work? Time mV High Density Low Density Coil Magnet
How does it work? Mass and density are measured. Volume is calculated. Volume (gal/min) = Mass rate (lb/min) Density (lb/gal)
