Abstract

Disclosure is made of a method and apparatus for monitoring a conduit system for an incompressible fluid for leaks, wherein a testing fluid is introduced into the conduit system during a testing period when no fluid is being withdrawn from the conduit system and the conduit system is closed on the supply side by a main valve. Now, without increasing the pressure in the conduit system, a check is to be made whether fluid is escaping from the conduit system despite the closed withdrawal valve. For this purpose, without the entry of testing fluid from the supply side of the main valve (1), a predetermined test volume of the testing fluid is introduced into the conduit system (8) under a pressure of the same order as the fluid pressure on the supply side of the main valve (1) and the time required by the test volume to flow into the conduit system is measured. A suitable apparatus for this comprises a chamber (12) for introducing the test fluid into the conduit system, the chamber communicating only with the conduit system (8) and having a volume which can be changed between a predetermined first larger value and a predetermined second smaller value. Further, time measuring means (16) are provided for measuring the time during which the chamber changes from the first volume to the second volume. Single figure.
