DEVICE OF OPENING OF UNIVERSAL PLATFORM FOR MONITORING OF MEDIUM PARAMETERS IN PIPELINE Russian patent published in 2024 - IPC G01F1/44 F17D3/01 

FIELD: measurement.

SUBSTANCE: invention relates to measurement of multiphase fluid flow parameters and can be used in information-measuring systems of oil producing and oil processing industries. Opening device of universal platform for monitoring of medium parameters in pipeline represents radial through hole of round cross-section with three stepwise variable diameters with formation of two thrust sites. Said hole is made in the wall of the measuring unit of the platform in the form of a Venturi tube in the area of the neck in the cross-sectional plane transverse to the direction of flow of the medium. In the hole there is a window which is transparent for radiation in a given frequency range. On the surface of the thrust site located closer to the inner channel of the measuring unit of the platform, there is an annular groove in which a sealing gasket is installed, and a radial boss. Blind holes with internal thread are made along the circumference at equal intervals on the surface of the thrust site located closer to the external surface of the housing. Window has a cylindrical shape with a stepwise variable diameter to form a mating support platform. End surface of the window located on the side of the internal channel of the measuring unit of the platform is concave and cylindrical with a radius equal to the radius of the section of the internal channel of the measuring unit of the platform. On the thrust site located closer to the outer surface of the housing of the measuring unit of the platform there is a flange fixed by a threaded connection in blind holes.

EFFECT: proposed device of platform opening provides its reliable tightness, enables to use various types of analysers and to replace windows without complicated measures for its dismantling, and also provides a laminar flow of the medium in the parameters monitoring zone, reducing the error of the obtained data.
