Use can be made as a measuring device for the liquid level (3, 4) in a container (1) of an electrically heated resistive conductor which has temperature-dependent resistance coefficients and whose resistance is measured by a bridge circuit (12). In this arrangement, resistive conductors (8, 10) having a positive temperature coefficient, and resistive conductors (9, 11) having a negative temperature coefficient are connected alternatively in series as a chain (7) in one bridge arm (7), and a plurality of such chains (7) are arranged adjacent in the vertical direction in the container (1), so that the mutually offset resistive conductors produce measured values which can be evaluated digitally. The invention serves, in particular, for determining the liquid level in the reactor pressure vessel (1) of a nuclear reactor. <IMAGE>
