A method for calibration of level measuring channel in polymetric system includes measurement of the level with reflectometric method, reception of signal reflected by wave impedance irregularities on sensitive element, measurement of delay time of reflected signal with respect to probing one, processing in calculator, display on indicator. Calibration is carried out with liquid in vessel, with changing the filling level, which is controlled with reference system of measurement of distance (level), and a temperature of electronic block. Time delay for signals reflected from the interface region and the value of temperature of electronic block are stored with software of measuring channel together with respective value of distance to the interface region, after that correspondence of readings of polymetric system to readings for the distance to the interface region obtained by reference system of measurement of distance (level) is determined. |
