METHOD AND DEVICE FOR MEASURING MASS FLOW OF GAS-LIQUID MIXTURE

摘要

FIELD: measurement technology.;SUBSTANCE: oil-gas mixture is divided to liquid and gaseous phases by means of separator connected with container. Space of container between two levels which limit the space is filled with liquid phase and, when emptying container, by gaseous phase. Times of filling and emptying of volume are registered simultaneously. Container is provided with scales for registering change in expulsive force in time, which force acts on hollow body connected with scale. The body has calibrated volume and calibrated height. It is provided with flat edges. The body is disposed in container inside area of mentioned volume. Container in the area of body disposition has calibrated area of internal cavity's cross-section. Container is subject to filling in and emptying till liquid covers body completely or till level of liquid goes downs lower than body's border. Maximal and minimal readings of scales achieved during time of filling in and emptying are used for measuring densities of liquid and gaseous phases and their mass flows from given design formulas. Mass flow can be determined without necessity of calibration for height of volume of liquid and distance between levels of filling.;EFFECT: simplified procedure of measurement; improved precision.;2 cl, 3 dwg
