Magnetic resonance multiphase flowmeter M-PHASE 5000 for the simultaneous measurement of oil, gas and water: - Single measurement principle, no radioactive source - Fully automated inline fluid characterisation - Large dynamic range up to 1:60, full bore design - Enhanced reservoir management Magnetic resonance makes use of a fundamental property of atoms and in effect makes it possible to “count” hydrogen atoms. Since oil, gas and water all contain hydrogen atoms, multiphase flow can be measured using magnetic resonance. For this purpose the fluids are magnetised and subsequently excited by radio frequency pulses. The hydrogen atoms respond to the pulses and send back echoes which are recorded. The amplitude of the echoes and the rate at which they decay is used to calculate the flow rates. The difference in magnetic resonance properties allows making a distinction between the flowrates of oil, gas and water.
