Claim 14:
15. A method of producing a system for determining a water cut of a water/oil emulsion, the method comprising:
providing 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;
coupling the water cut sensor to a feed line;
coupling an alternating current source to the inductive coil via the feed line;
coupling a processor to the inductive coil via the feedline or coupling the processor to an acoustic sensor, wherein the processor is configured to determine the water cut of the water/oil emulsion based on a resonant frequency of the magnetoelastic ribbon,
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.
