Abstract

A device for location of the points of loss in a pressure pipe-line comprises two measuring channels. One channel consists of a converter (1) for converting mechanical oscillations into electric signals, whose output is connected with the input of an amplifier (3) whose output is connected with one of the inputs of a limiting unit (5), a limiting level control unit (7) with its output connected to another input of the limiting unit (5) whose output is connected with the input of a pulse former (9) its output being connected with the input of a variable delay unit (11). Another measuring channel consists of a converter (2) for converting mechanical oscillations into electric signals whose output is connected with one of the inputs of a limiting unit (6), a limiting level control unit (8) with its output connected to another input of the limiting unit (6), its output being connected with the input of a pulse former (10). The device comprises as well an impulse coincidence circuit (13) one of the inputs of which is connected with the output of the variable delay unit (11) and another - with the output of the pulse former (10). The output of the impulse coincidence circuit (13) is connected with the input of an impulse coincidence counter (14) whose output is connected with the input of an oscillator (15).
