A mathematical model of pulsed reflectometric level gauge is constructed, which takes into account inhomogeneities in the path of probing signal in microwave tract. A computer model was implemented in SimInTech dynamic simulation environment. The mathematical model is universal, which makes it possible to introduce additional inhomogeneities and study the influence of probing pulse temporal parameters: duration, period, and duty cycle. In addition, the authors propose a method to compensate for the influence of temperature and pressure in primary circuit of nuclear power plant on the accuracy of measuring the coolant level by introducing additional reference marks in the sensitive element of pulsed reflectometric level gauge.
Key words: : reflectometric level gauge, pulsed reflectometer, mathematical model, nuclear power plant, computer model, SimInTech.
