Grahic Jump Location
MCFM transmitter and sensor configuration to measure galvanic and displacement currents with a sensor electrode covered by an insulating film
Grahic Jump Location
Crossplot of MCFM measured water holdups (Hw) in oil/water flow. The lines indicate the ±4 percent error range.
Grahic Jump Location
Ternary diagram of holdups measured in stratified 3-phase flow with a constant gas rate (Hg=gas holdup, Ho=oil holdup, and Hw=water)
Grahic Jump Location
MCFM sensors in a velocity array configured for simultaneous measurement of slug front or tail velocities, and dispersed phase velocities. Ca,b represents the correlation of the signal variations from sensors a and b.
