Abstract: The present invention is directed to both a method for ensuring optimal conditions for separation, and a separator device for extraction of water, oil and gas from a mixture of water-oil-gas flowing in a straight pipe or straight channel. A separator comprises a certain length of pipe with diameter larger than or equal an inlet pipe and several inclined and profiled holes along the separator pipe wall. Holes in the pipe wall at the bottom of the pipe are provided for extraction of water, and one or more groups of inclined holes in the pipe wall at the top of the pipe are provided for extraction of oil and possible gas. Water and oil/gas are separated such that dispersed flow in the inlet is reduced to velocity equal or less than that of the separated flow at the outlet of the separator.

Abstract: Device for mounting and demounting of a probe to be arranged in an access tube to a process pipeline, including a hydraulic cylinder accessing the access tube with a gripping tool to engage a probe for moving this probe into an operating position in the access tube and retrieving the probe from this position. A revolving unit with at least two chambers is provided, each chamber accommodating an axially movable probe. The chambers are accessible by the gripping tool to move a probe into a chamber and, in a subsequent step, from the chamber into the access tube. A powering device is arranged for revolving the revolving unit.

Abstract: Flow measuring method and device for measuring the velocity of a single-phase or multi-phase flow. The method includes calculating the flow velocity U only by measuring consecutive values of pressure p, temperature T and momentum D, and then calculating the change in pressure ?p, change in temperature ?T and change in momentum ?D. The device includes a probe with a housing having electronic components connected to different sensors in the probe. The probe has a long, hollow momentum tube, fastened by its first end to the housing and a hollow, cylindrical sensor tube, located inside the momentum tube fastened by its first end to the first end of the momentum tube. The sensor tube includes plate capacitors located on the outside of the second end, and is thereby able to measure the conductance between the momentum tube and the plate capacitors on the sensing tube. The probe has a pressure sensor and a temperature sensor.
