摘要： A system for controlling the pumping rate of a producing well using a rod pump in which a vibration sensor 95 is attached to the above ground pump structure. A processor 96 analyses signals from the vibration system sensor 95 to identify vibrations indicating the occurrence of fluid pound and controls the speed of the rod pump accordingly.

摘要： The vapor phase and the liquid phase of the two-phase fluid flow, for example wet steam, are separated. The vapor phase flows in a vapor line (13) having an orifice (12) with pressure taps (14,15) on either side. The liquid phase flows in a bypass line (25) having an orifice (26) with pressure taps (27,28) on either side. The mass flow rate of each phase is obtained from the upstream pressure and pressure drop measurements across the orifices. The phases are recombined in the plane of symmetry of the output line (11). The liquid flow rate through the bypass line is controlled by a valve (23) responsive to the mass flow rate measurements.
