Primayer Eureka 2R Leak Noise Correlator Stock #230228A Included with Sale -Eureka 2R Head Unit -x2 Eureka Transmitters -x2 Transmitter Wands -Antennas for All Units -Hard Padded Transport Case -Power Adapter/Charger About the Unit: Primayer Eureka 2R  Eureka2 is an advanced system for the accurate pinpointing of underground fluid leaks, prior to excavation. The system has been proven to perform world-wide and can be used effectively on all types of pipe – not only metallic, but also plastic and asbestos cement. Taking advantage of new technologies and innovative ideas, Primayer has made important enhancement to the well established Eureka leak noise correlator. The Eureka2R models provide the definitive tools for routine leak location activities. Despite its high level of sophisticated technology, Eureka2 is designed to be easy to use, extremely rugged, small and lightweight. Leak Noise Detection Leak noise correlation is used to detect leaks in pipes with a positive internal pressure, where leaks allow a loss of flow to the outside. The movement of fluid through the leak causes rapid pressure changes around the site of the leak, establishing a noise source at the leak. This noise travels in both directions, at the same velocity, along the pipe from the leak. These principles are used to determine the leak location. Note: Noise is not a constant frequency, like a musical note, but a random and constantly changing blend of different frequencies. The correlator operates on this principle. Methods for Locating Leaks Previous methods of leak location relied on an initial detection of a noise,which was then traced along ground level to identify the location of the maximum noise. The assumption was that this location was directly above the location of the leak. The equipment used for this method included listening sticks and stethoscopes, but these were difficult to use if the noise proved toofaint or loud for accurate location. Background noise was another problem; therefore, electronically-filtered amplifiers were introduced in an attempt to overcome such problems.  A correlator operates by comparing the noise detected at two different points in the pipeline. Noise travels from the leak in both directions along the pipeline at a constant velocity (depending on several factors). Therefore, if the leak occurs at an equidistant location between the two sensors, these sensors will detect the noise at the same time. Conversely, if the leak does not occur at an equidistant location, then the sensors will detect the same noise at different times. This correlator measures this difference (delay) in time. The following diagram provides an illustration of this principle: Assume the sensors are located on valves A and B (convenient access points for underground pipes). However, the leak occurs closer to valve A.By the time a particular noise from the leak has reached A, the same noise heading towards B has travelled only as far as X. The distance from X to B causes a delay (t) before the noise arrives at B. Therefore, the correlator detects the delay (t) between the arrival of the noise at A and B. Assume the velocity of sound is V and the distance between the sensors is D. As the distance from X to B = V * t (velocity x time), then D = (2 * L) + (V * t). This equation may be rearranged to provide L, the distance from the sensor closer to the leak site: The sound velocity can be calculated based on the pipe diameter and material, and the distance between the sensors can be determined by careful measurement. Therefore, the correlator can calculate and display the location of the leak as a direct distance from the closer sensor. The correlator also may be used to measure the actual velocity of sound in the pipe under investigation, ensuring the greatest accuracy in locating the leak. Note: This discussion assumes the correlator is connected directly to both sensors. Since this is often impractical, the connections typically are made using radio links with negligible delays. However, the principle remains the same. ------------------------------------------------------------------------ Detailed Images Below ------------------------------------------------------------------------ Trade Ins:  We offer some of the highest prices on your used test equipment.
