METHOD FOR MEASUREMENT OF LEVEL OF LIQUID AND DETERMINATION OF POSITION OF THE INTERFACE OF LIQUIDS WITH DIFFERENT DENSITY

摘要

The invention relates to the area of measuring engineering and metrology and can be used for measurement of position of the interface of liquids with different densities. The method for measurement of level of liquid and determination of position of interface of liquids is in determination of value of change of time intervals between sending of measured signal and reception of reflected from surface of liquid and surface of reflector – phase divider signal , those are proportional to level of liquid and position of the interface of phases of the controlled medium. Technical result of the invention is in increase of accuracy of measurements and increase of working range of the measuring devices.
