Vista Research, Inc. Offers Innovative Products To Detect Leaks in Aircraft De-Icing Fluid Systems.Business Editors SUNNYVALE, Calif.--(BUSINESS WIRE)--Oct. 24, 2001 Vista Research, Inc.'s non-invasive leak-detection technology is now being used to test aircraft de-icing fluid as well as fueling systems. The leak detection technology is both more accurate and less expensive than other integrity testing Integrity Testing, is a name given to the Non destructive testing of piled foundations. It was used or started back in the late 1960's and has developed over the years by many companies In Europe CEBTP in Asia and Australia by Integrity Testing, and USA by GRL. methods available to system owners. Vista's line of products, which can detect and locate leaks in one hour, offers "greater accuracy, lower risks and a shortened timeline," said Mike Fierro, Vista vice president. Additional cost savings can result from the fact that the same equipment can be used for monitoring both fuel and de-icing systems. Vista's innovative system works by calculating the expected change in fluid volume as the outside ground and air conditions cause temperature changes in the pipeline contents. If the fluid volume does not change in accordance with the expectations, it is an indication that there is a leak in the system. Introduced six years ago, Vista equipment is currently used on fuel distribution and storage systems at major airports in the United States List of airports in the United States, grouped by state or territory and sorted by city. Due to the large number of airports in the United States, this page only lists public use airports providing scheduled passenger services with over 10,000 passenger boardings per year and Canada, including New York New York, state, United States New York, Middle Atlantic state of the United States. It is bordered by Vermont, Massachusetts, Connecticut, and the Atlantic Ocean (E), New Jersey and Pennsylvania (S), Lakes Erie and Ontario and the Canadian province of , Boston, Dallas, San Francisco San Francisco (săn frănsĭs`kō), city (1990 pop. 723,959), coextensive with San Francisco co., W Calif., on the tip of a peninsula between the Pacific Ocean and San Francisco Bay, which are connected by the strait known as the Golden , Montreal and Toronto. The active ingredients An active ingredient, also active pharmaceutical ingredient (or API), is the substance in a drug that is pharmaceutically active. Some medications may contain more than one active ingredient. in de-icing fluids are typically either propylene glycol propylene glycol a chemical used industrially as an antifreeze, solvent stabilizer, as a preservative in liquid livestock feeds and pharmaceutically as a vehicle or solvent for medicinal preparations. (PG) or ethylene glycol ethylene glycol: see glycol. ethylene glycol Simplest member of the glycol family, also called 1,2-ethanediol (HOCH2CH2OH). It is a colourless, oily liquid with a mild odour and sweet taste. (EG), and can account for as much as 50 percent of the composition of the fluid. U.S. law requires facilities using or storing EG-based chemicals to track and report their use and conduct periodic testing of the storage and dispensing systems. Previously used test methods required significant time and resources and some generated waste that required special handling. Vista's products, the HT-100 and the LT-100, can determine the integrity of a piping system in about one hour. "They avoid injecting additives, waiting for diffusion into the soil to occur, conducting expensive boring and excavations and then waiting for lab tests," said Fierro. "There also is no waste of de-icing fluid and no cleanup afterwards af·ter·ward also af·ter·wards adv.

If a leak is detected in the piping system, Vista's leak location system, PALS, is available to locate it quickly. PALS is an innovative leak location technique using sensors attached to accessible points on the line eliminating the need for excavation. Leaks can be pinpointed to within 1.5% of the sensor separation, e.g. within 8 feet on a 500-foot segment of line. Vista's headquarters are located here in the heart of Silicon Valley.
