  • Patent number: 8370089
    Abstract: A method and equipment are provided for determining the level/height, of one or more interfaces between two or more fluid phases of different density that are contained in a vessel, tank or the like. The position of the different interfaces in a tank is determined by measuring the pressure thereby determining the density of the fluid over the height of the tank by using a pressure measuring rod, equipped with pressure sensors, positioned in the tank. A mathematical model or algorithm is used which calculates how the density and hence the pressure vary over the height of the tank as a function of the fluid properties of the respective fluids in the tank, the interface, on the basis of the density being the same within each layer of the respective fluid, as a respective point at which the density changes from one layer to the next in the tank.

  • Patent number: 8171785
    Abstract: A method calculates the boundary layer level between fluids, in particular the boundary layer level between oil and water in connection with the use of a segment-based boundary layer meter. The calculations are based on the use of measurement signals from a number of segments, n, and the boundary layer level, L, of the water is calculated as follows: L = ? _ - ? 0 ? v - ? 0 ? ( L u - L l ) + L l where: Lu Upper water range area Ll Lower water range area ?n Density of segment no. n from the profile meter {circumflex over (?)}n Corrected density for segment no. n ? Calculated mean density ?v Mean density of water from the profile meter ?o Mean density of oil from the profile meter N Total number of segments included.

  • Publication number: 20110252893
    Abstract: A device for measuring rates in individual phases of a multiphase flow, such as in flow of hydrocarbon fluid through a pipe line, comprising a venturi having, seen in the flow direction thereof, a first inlet portion with deceasing cross-section, a second intermediate portion with mainly uniform cross-section, and a third outlet portion with increasing cross-section, and being situated within the pipe line. According to the present invention, the venturi is provided with a number of sensors, and the sensors are arranged in mutual distance at different cross-section areas along at least the first of the three portion of the venturi as thereby being able to determine a pressure profile along the venturi as a base for estimating rates for actual rates of the flow.
