Zusammenfassung:The invention relates to measuring engineering and can be used at measurement of level, limits of distribution and density of liquid and bulk media. Method for determination of characteristic of transformation pf unit for determination of parameters of liquid and bulk media by delay of reflected signal with respect to probing pulse signal sent to controlled medium is in fact that one performs set of shifts of probing pulse signal along range of measurement by given time intervals, with obtaining representation of set of shifted probing pulse signals at one reflectogram, one determines time intervals between representations of shifted probing pulses obtained in reflectorgam, and determines characteristic of transformation for determination of parameters of liquid and bulk media along range of measurement, with bringing to correspondence given time intervals by which probing pulse signal has been shifted, and respective time intervals between representations of shifted probing pulse signals obtained in reflectogram. The invention provides compensation of error related to non-linearity of the characteristic and can be used for correction of results of measurements in process of operation of the unit, this promotes increase of reliability and accuracy of results obtained.
