FIELD: measuring equipment. SUBSTANCE: level meter has wave-guide made of ferromagnetic material and mounted for permitting free displacement with respect to receiving and emitting units. One end of the wave-guide is connected with a damping member and secured to a float. The receiving and emitting units are fixed at a given distance from each other. Each unit is constructed as coil mounted coaxially on the wave-duct and permanent magnet. The receiving unit is arranged from the free end of the wave- guide. The first amplifier is connected to the coil of the receiving unit. The output of a generator of working pulses is connected to the emitting unit through an amplifier and to the first inputs of pulse counter and flip-flop. The second inlet of the flip-flop is connected to the output of the first amplifier. EFFECT: improved design. 1 dwg
