Abstract

Controlling the operation of a hydrocyclone to maintain the hydrocyclone in a desired operational state as it separates a pumped fluid into an overflow stream and an underflow stream is described. The method comprises measuring vibrations of the hydrocyclone at a selected frequency within a predetermined frequency range; comparing a characteristic of the measured vibrations at the selected frequency with a plurality of values representing transitions between different operational states of the hydrocyclone to identify a current operational state of the hydrocyclone; and generating an adjustment setting to change the identified current operational state to the desired operational state, where the adjustment setting increases or decreases a pumped fluid parameter.
