Continuous Cable Leak Detection
Continuous leak detection sensing cable offers the most accurate method of leak detection. Sensor cable systems are capable of locating multiple leaks without loss of accuracy and sensitivity. Leak locations can be determined to within 5 feet of source. Sensor cables utilize Time Domain Reflectometry technology as the basis of leak detection. The technology operates similar to radar. Thousands of times each minute, safe energy pulses are sent out on the sensor cables. As these energy pulses travel down the cable, reflections are returned to the monitoring unit and a "map" of the reflected energy from the cable is stored in memory. The presence of liquids on the sensor cable, in sufficient quantities to "wet" the cable, will alter its electrical properties. This alteration will cause a change of the reflection at that location. The alteration is then used to determine the location of a potential leak to within five feet.
