LEAK DETECTION BASICS Leak Detection Basics The Environmental Protection Agency (EPA) has directed underground transport of hazardous materials be protected from release into the environment in its Standard 40 CFR, Part 280 & 281. Our Duo-Pro®, Poly-Flo®, and Pro-Lock™ systems have been specifically engineered to exceed the piping system requirements of the EPA. However, an important additional aspect of the EPA requirement is the specification for leak detection systems in all buried systems. Pressurized systems must have automated leak detection, which are wired to shut-off valves in case...

LEAK DETECTION BASICS valve to the on position. The system integrity is ensured when no media is present after opening. A solid Dogbone® can be utilized as a means of zoning a system. Systems with solid Dogbones® minimize and compartmentalize area where a leak may occur. This design helps minimize potential costs to find and repair a leak. Manual Leak Detection Features, Benefits and Limitations - Simplified system engineering - Cost effective installation - Relies on manual (human) operation - Locates leaks within a zone or sector of a system - Does not accurately pinpoint leaks - Can be...

LEAK DETECTION BASICS Pal-At® Leak Detection/Location Monitoring Units Pal-At® Monitoring Systems are microprocessor based units capable of the continous monitoring of a sensor string for leaks, breaks and shorts. The units have sensing ranges of 2,000; 5,000; 10,000; or 15,000 feet per cable with up to 8 cables per panel. The alarm unit operates on the principle of pulsed energy reflection and maps the entire length of the sensor cable. A digitalized system map is stored in nonvolatile memory. Alarm panels provide continous indication that the sensor cable is being monitored. Pal-At...
