Detection Method Detection underground liquid pipe (T) in the leakage of the liquid pipe underground water pipes in particular, according to the method of: injecting a gas through a diffuser (8) to the fluid conduit, the gas in the The content of the atmosphere is small; and in the ...
Detecting leaks in plastic pipes O Hunaidi,W Chu,A Wang,... - 《Journal ‐ American Water Works Association》 被引量: 177发表: 2000年 A New Method for Detecting Leaks in Underground Water Pipelines In most water distribution systems, a fairly sizable amount of water is lost because of lea...
Reliable and quick techniques are needed to locate and estimate leaks in pressurised pipe systems in order to reduce water loss as much as possible. The aim of the present paper is to show that the use of unsteady-state tests, which give rise to small overpressure, can be considered as an...

An apparatus for permanently or semi-permanently fitting to an underground water pipe 15,16 for detecting leaks therein, comprises a hydrophone 26 mounted to acoustically monitor water flowing along the pipe 15,16 and means 29 for analysing a parameter of the output signal of the hydrophone 26 ...
Detecting leaks in pipes carrying liquid or gases German Patent DE19501044 Kind Code: A1 Abstract: The procedure uses convention gas meters to measure the flow rate in pipes. One meter (2) is placed at the start of the pipe (5). Other meters (2b,2c,2d) are at the point where the ...
GPR identify leaks in buried water pipes either by detecting underground voids created by the leaking water as it erodes the material around the pipe or by detecting anomalous change in the properties of the materials around pipes due ... TST Amran,MSM Amin,MR Ahmad - International Nuclear Scie...

Southwest Research Institute (SwRI) has created the next generation of transducers that use ultrasonic guided wave technology to detect anomalies in pipes, enabling users to prevent leaks before they start. The device, which utilizes the SwRI-developed Magnetostrictive Sensor (MsS) technology, will be...
There is a need for detecting contamination, for example due to leaks from underground tanks and pipes, particularly tanks that were installed decades ago, using a nondestructive and non-invasive method that is at the same time economical and efficient. Once these leaks are detected, there is a...
