摘要：the thermal system for measuring liquid level, comprising a temperature sensorand a measuring resistance (2), and a heating resistance (3) in the casing (1).the resistanceheater (2) is driven in a pulse regime.the signal from the resistance measurement is
connected to the inputs of two fittres (20, 22), taking the continuous component and thealternating component of the measurement signal.a calculation module (29), the value ofliquid level and temperature are determined from the output signals of the filter (20).22),and a signal provided by temperature measurement means (12, 13) of the liquid and thegas above the liquid medium.
