This book was released on 1979 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: A program was conducted to determine repeatability and linearity of the ultrasonic time-delay types of flowmeters, so that their applicability to leak detection on underwater pipelines could be assessed. Field tests using merchantable crude oil were conducted on two off-the-shelf, commercially available flowmeters at a refinery meter proving station. These tests showed a short-term repeatability of 0.2 percent for both meters. Long-term (7 hours) repeatability was 0.6 percent for one meter and 2.5 percent for the other. For a leak detection system in which line balance is continually computed and line packing is compensated for, slow drifts in line balance due to drifts of meter factors can be compensated for by periodically adjusting meter factors. For a meter with drift characteristics similar to those measured, a computerized simulation indicates that the probability of detecting a leak greater than 0.6 of the total flow in 10 minutes is greater than 99 percent. The probability of a false alarm for the same conditions is about once per week. (Author).

Book excerpt: Ageing infrastructure and declining water resources are major concerns with a growing global population. Controlling water loss has therefore become a priority for water utilities around the world. In order to improve efficiencies, water utilities need to apply good practices in leak detection. Leak Detection: Technology and Implementation assists water utilities with the development and implementation of leak detection programs. Leak detection and repair is one of the components of controlling water loss. In addition, techniques are discussed within this book and relevant case studies are presented. The book provides useful and practical information on leakage issues.

This book was released on 1970 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: A computer simulation program in conjunction with an instrument systems analysis program lead to the conclusion that microwave radiometry working in concert with thermal infrared systems could detect petroleum product pipeline leaks. The utilization of these systems from an airborne platform would result in a low false alarm rate and a high probability of leak detection. A demonstration experiment was designed to test the simulation program. This demonstration was carried out in west Texas along three different pipeline sections with eighteen individual leak circumstances. All data, airborne and ground, was reduced, correlated and analyzed to demonstrate remote sensor capabilities. It was found that the apparent microwave (13.7 GHz) temperature of a leak increases significantly compared to surface material containing no oil. Also, a soil containing oil caused a decrease in polarization contrast. Thermal infrared showed a warm area surrounded by a cool halo. When these circumstances all occurred together a leak was identified, proving the correctness of the original computer simulations.
