  • Method for determining pump flow rate
    Patent number: 9464925
    Abstract: The present invention relates to a method for determining a flow rate indicator relating to the output flow rate of one or more activated pumps of a pumping station. The pumping station includes a well configured to receive or supply fluid flow. The method includes the step of determining, using a computational device, an operating condition relating to the activated pumps. The activated pumps are temporarily deactivated and a well flow rate relating to the fluid flow is determined, responsive to the determination of the operating condition. The method further includes the step of determining the pump output flow rate indicator using the determined well flow rate. The step of temporarily deactivating the activated pumps involves deactivating the activated pumps for a predetermined period of time and determining the well flow rate over that period of time.

  • Method for determining pump flow rate
    Patent number: 8956125
    Abstract: The present invention relates to a method for determining a flow rate indicator relating to the output flow rate of one or more activated pumps of a pumping station. The pumping station includes a well to be at least partially emptied by the pumps and an inlet through which inflow can be supplied into the well. The method includes the step of determining, using a computational device, an operating condition relating to the activated pumps. The pumps are temporarily deactivated and an inflow rate indicator relating to the inflow is determined using the computational device, responsive to the determination of the operating condition. The method further includes the step of determining, using the computational device, the flow rate indicator using the determined inflow rate indicator. The present invention is equally applicable to a well to be at least partially filled by the pumps.
