FIELD: chemistry.SUBSTANCE: fuel or air stream is passed at a constant rate through a water separator consisting of multiple cells arranged in series one after the other, formed by a coagulator and a separating grid, and water obtained from separation on a porous partition wall is removed into a settling tank. Pressure in front and behind the partition wall is constantly or periodically measured; information on the pressure measurements is transmitted to an analytical recording unit; hydraulic resistance of the porous partition wall is calculated based on the pressure difference; the obtained data are then used to determine the amount of water retained by the porous polyvinyl formal of the coagulator; based on the obtained calibration data on change in hydraulic resistance of the porous partition wall depending on water content in the coagulator and in the fuel stream, and based on said data, the amount of water contained in the fuel is determined. An apparatus for realising the method is also described.EFFECT: high accuracy and reliability, easy determination.8 cl, 2 dwg |
