ABSTRACT:
The invention relates to a process and to a device for regulating a multiphase pumping assembly that includes notably at least one multiphase pump (1), a device (6) for determining a parameter representative of a working instability of multiphase pump (1) and at least one programmed processing assembly (7) allowing to store at least the determined parameter and initial parameter values, and to compute the new value of the speed of said multiphase pump in order to bring the working point of the pump back into its operating range.
