摘要： The present invention relates to a method and a device for measuring volume flow rates of liquid phase components and gas and determinating their volume concentrations in a multiphase mixture along a pipeline. Measurements are executed with an ultrasonic system which includes a set of local acoustic transducers arranged in the interior of the pipeline. Each pair of an emitter and a receiver of the transducer forms a sampling volume of a medium being under control. Volume concentrations of mixture components are determined by timing of passage of acoustic pulses through the sampling volume of the medium. Volume flow rates of the mixture components are calculated by measuring phase velocities and volume concentrations in two pipeline divisions with different cross-section areas located in series at a distance one from the other in flow direction.

摘要： A device for determining a density of a fluid is described. The devices comprises a mechanical resonator, a driver/receiver unit arranged to provide an actuation to the mechanical resonator, sense a response of the mechanical resonator to the actuation, and provide an output signal representing the response; and an evaluation unit. The evaluation unit of the device is arranged to i. determine an oscillation distribution from the output signal, ii. determine a resonance frequency estimate from the oscillation distribution, and iii. determine the density of the fluid based upon the resonance frequency estimate. The device according to the invention enables a more accurate determination of the fluid density for fluids comprising immiscible components (thus forming a heterogeneous mixture), like a water-oil emulsion, or a fluid with occluded gas.

摘要： The method and apparatus for simultaneous measuring volume flowrates of the liquid phase components and the gas and determining their volume concentrations in a multiphase oil/water/gas mixture flowing through a vertical pipeline. Measurements are executed with the local electroacoustic system which includes a set of microemitters and receivers of acoustic signals arranged in the interior of the pipeline. Every pair of emitter-receiver forms a local volume of the medium being under control. Volume concentrations of the mixture components are determined by timing the passage of the acoustic pulses through the multiphase medium being sensed. Volume flowrates of mixture components are calculated by measuring the gas phase velocity in two pipeline cross-sections with different areas on the basis of cross-correlation or Doppler methods.
