Advances in sensor technology and signal processing have allowed the construction of Coriolis
flowmeters employing straighter tubes than the U-tube unit previously illustrated and photographed.
Straighter tubes are advantageous for reasons of reduced plugging potential and the ability to easily
drain all liquids out of the flowmeter when needed. In straight-tube Coriolis flowmeters, we still
find the same general design of a force coil flanked by matching sensor coils measuring vibration
frequency (for density measurement) and phase shift (for mass flow measurement).
