  • Patent number: 9083213
    Abstract: A microgenerator for use in petroleum distribution systems includes a casing defining an interior portion and an exterior portion. The casing has an opposed first support wall and second support wall coupled within an inner diameter of a cylinder containment wall. At least one fluid inlet penetrates the cylinder containment wall. The fluid inlet is fluidly coupled to an energized fluid source. At least one nozzle is fluidly coupled to the fluid inlet. The nozzle is configured to accelerate the fluid into the interior portion. At least one fluid outlet penetrates the cylinder containment wall. The fluid outlet is configured to discharge the fluid from said interior portion of the casing. An impulse turbine is located within the interior portion. The turbine has a first stator coupled to the first support wall and a second stator coupled to the second support wall opposite the first stator. A rotor is rotatably mounted between the first stator and the second stator on a shaft at a central axis of the rotor.

  • Patent number: 7032449
    Abstract: A sensor for measuring properties of a fluid in a vessel, includes a sensor mount adapted to mount within a wall of a vessel; a sensor body extending substantially vertically from the sensor mount; and a plurality of sensors spaced vertically along the sensor body, whereby at least one of level, density, temperature and pressure of fluid in the vessel can be measured.

  • Patent number: 6257070
    Abstract: A method for determining real time liquid phase flow rate from a biphase stream includes the steps of: providing a stream of a biphase fluid including a gas phase having a known gas density and a liquid phase having a known liquid density; providing a separator having a known volume gradient corresponding to liquid level in the separator; feeding the stream to the separator so as to provide a separated liquid phase containing a portion or the gas phase as entrapped gas and a separated free gas phase in the separator; measuring density of the separated liquid phase; measuring change in level over time of the separated liquid phase in the separator; and determining a liquid phase flow rate from the change in level over time, the separated liquid phase density, the known gas density and the known liquid density.
