Claim 0:
1. A system for determining a water cut of a water/oil emulsion, the system comprising:
a water cut sensor comprising a magnetoelastic ribbon and an inductive coil arranged proximate to the magnetoelastic ribbon so that an electromagnetic field produced by the inductive coil electromagnetically excites the magnetoelastic ribbon;
an alternating current source;
a processor configured to determine the water cut of the water/oil emulsion based on a resonant frequency of the magnetoelastic ribbon while the magnetoelastic ribbon is excited by electromagnetic field produced by the inductive coil, wherein the processor is further configured to determine that the water cut sensor is surrounded by an air/gas mixture when the resonant frequency is lower than a resonant frequency corresponding to a 90% water cut; and
a feed line coupled to the water cut sensor, wherein the feed line includes an electrical coupling between the alternating current source and the inductive coil of the water cut sensor,
wherein the feed line includes an electrical coupling between the processor and the inductive coil of the water cut sensor or the processor is coupled to an acoustic sensor.
