Abstract
A pipe leakage detection system which includes a flexible probe with a body portion of sufficient length to pass along a pipe. Pairs of seals define a seal volume with the inner pipe wall. An adjacent test region can be used to determine leakage. A source of fluid pressure is applied to lines. With equal pressure in both seal and test regions as indicated by a manometer no leak will occur around the seals. A deliberate outgoing flow rate is allowed from a line and any differential in flow, as detected by flow meters, will indicate an actual leakage rate.
