A processor analyzes the signal generated by each sensor to determine one or both of the initial fluid flow rate and initial fluid pressure at the marking locations.

  • Publication number: 20140373638
    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.

  • Patent number: 8916074
    Abstract: According to a method for making a resin hollow body, in a primary-formation process, molten resin is injected into spaces defined by dies to form resin components. In a die-moving process, each component is held in at least one die. Joining edges of the components are brought close through relative movement of the dies to make a predetermined arrangement of the components. In a secondary-formation process, molten resin is injected into a region where the edges are adjacent. The edges are joined to form an outer wall, partition wall, and hollow portion of the hollow body. At least one of the edges constituting the partition wall includes a linear groove. In the die-moving process, the partition-wall-constituting edges are brought into contact to define by the groove a linear hollow cavity surrounded with the edges. In the secondary-formation process, the cavity is filled with molten resin to join the partition-wall-constituting edges.

  • Patent number: 8910529
    Abstract: A gas flow-rate verification system includes: process gas lines each being arranged to supply gas from a process gas supply source to a process chamber through a first line cutoff valve, a second line a cutoff valve, and flow control device; and a shared gas line connected in a branch form to the process gas lines to discharge gas from a shared gas supply source through the second line cutoff valve and the flow control device. The shared gas line includes a shared cutoff valve, a measuring tank, a first pressure sensor, and a pressure regulating valve. When the first line cutoff valve and the shared cutoff valve are closed, the first pressure sensor measures a pressure drop of gas in the tank to verify a flow rate of the flow control device. The pressure regulating valve feedback-controls secondary side pressure of the pressure regulating valve.
