Claim Text:
1. A method of monitoring operation of a liquid mixture separator, the separator comprising a vessel through which a mixture of different liquid components flows in a horizontal direction, the separator comprising a plurality of ultrasound transducers on a wall of the vessel at different heights at a common horizontal position along the horizontal direction, the method comprising transmitting ultrasound through the vessel from at least first part of the transducers and detecting ultrasound arriving at at least a second part of the transducers for a plurality of ultrasound wavelengths, including detecting a combination of response signals measured for ultrasound ray paths at mutually different angles to the horizontal, and between transducers of the first part and transducers of the second part at mutually different heights; fitting parameter values of a model that relates a parameter of a height dependent droplet size distribution to the detected combination of response signals.
