Patent
·
OSTI ID:6149499
An automatic fault locating apparatus for a pressurized pipeline comprises a pick-up having its output electrically associated with an input of an amplifier whose output is connected to one of inputs of an and gate having its other input connected to a pulse generator whereas an output of the and gate is connected to an input of a pulse counter. The apparatus further comprises an integration unit having an input connected to the output of the pick-up an amplitude limiter having its signal input connected to an output of the integration unit, a limit level adjusting unit whose output is connected to a control input of the amplitude limiter, a differentiation unit having its input connected to an output of the amplitude limiter, whereas an output thereof is connected to an input of the amplifier.
