Pipeline and leak locater and method
First Claim
1. A method of detecting a leak in a conduit, said method comprising;
- flowing a fluid through said conduit at super-atmospheric pressure,placing within said conduit a floatable leak sensor which is responsive to pressure, velocity and turbulence differentials caused by a leak in said conduit,moving said leak sensor through said conduit along with said fluid, said floatable leak sensor automatically stopping movement through said conduit

Abstract
A method and apparatus for detecting a leak in a conduit. The method generally comprises flowing a fluid through a conduit at superatmospheric pressure, placing within the conduit a floatable leak sensor which is responsive to pressure and velocity differentials caused by a leak, moving the leak sensor through the conduit along with the fluid, whereby the leak sensor stops movement through the conduit at the location of a leak. The apparatus comprises a leak sensor casing, a floatable leak sensor mounted within the casing for movement along with fluid through a line of test pipe, and means on the casing to attach casing to the test pipe to allow direct communication between fluid and the test pipe and the floatable leak sensor.

4. A pipeline and leak locator for detecting leaks in pipelines used for transferring fluids, comprising
a leak sensor casing, a floatable leak sensor mounted within said casing for movement along with fluid flowing through the line of a test pipe, said sensor being responsive to pressure, turbulence and, velocity differentials within said test pipe caused by a leak in said test pipe so that said sensor stops at said leak, and means on said casing to attach said casing to said test pipe to allow direct communication between fluid in said test pipe and said floatable
