Level meter has ultrasonic transformer connected to first output of generator and installed at the end of the wave guide placed in hermetic pipe at height of which measuring winding is distributed, floater with permanent magnet arranged as hollow cylinder, installed concentrically with tightened pipe with possibility of displacement in it, resolution block, at that the first ultrasonic transformer is arranged as receiving-transmitting, second amplifier, first and second pulse formers first inputs of which are combined and connected to the second output of generator first output of which is combined with output of ultrasonic transformer and connected to input of second amplifier as well output of which and output of the first amplifier are connected to the second outputs of the second and first pulse formers, respectively, outputs of those are connected to inputs of resolution block. There are included step-up and step-down voltage transformers. |
