PipePatrol Leak Detection Leak Detection PipePatrol is the most sensitive internal leak detection system available, providing accurate leak information for a high degree of safety. Its multi-method leak detection enables pipeline manage ent under both steady and transient pipeline conditions. This way, the LDS is able to m reliably distinguish between real leaks and imbalance deviations caused by line pack changes or separation units. PipePatrol Leak Detection can be retrofitted onto existing pipelines, using existing instrumentation. KROHNE also supplies complete project packages,...

► PipePatrol Leak Detection ^E-RTTM pipeline leak detection Extended Real-Time Transient Model (E-RTTM) E-RTTM is the only technology that allows fast and sensitive leak detection in any kind of pipeline operation. PipePatrol's unique leak pattern recognition is a proven technology that compares what is actually happening in a pipeline - without generating false alarms. Unlike other systems, it does not simply compare outlet flow with inlet flow. Instead, it uses the measured conditions to calculate the hydraulic profiles of the pipeline. One of these, the calculated flow profile, is...

PipePatrol Theft Detection Theft Detection PipePatrol Theft Detection uses dedicated pattern recognition, to provide fast and reliable identification and localisation of unauthorised or illegal product discharges, typically theft. Even for small volumes, the system initiates an alarm within minutes, making it possible to stop theft in the act. To alert the relevant staff, the system provides alarm reporting via e-mail, accompanied by Google Earth® integration showing the theft location, enabling a field team to take coordinated and swift action. For identification of the actual theft times...

PipePatrol Stress Monitoring Stress monitoring Pipelines are constantly working under mechanical stress during normal operations and load cycles. External influences, such as temperature extremes, mechanical shock or vibrations, can increase the local line pressure. Any design pressure violation can have a major effect on the pipeline lifetime. Modern regulations often now require operators to document and evaluate these effects. This PipePatrol module performs stress monitoring of the pipeline without human interaction and hence provides the base data for an assessment of the remaining...

PipePatrol Line Break Detection Line Break Detection Pipeline ruptures can result in dramatic consequences, endangering public safety and the environment. It is critical that fast acting rupture detection, response systems and procedures are designed, structured, and executed effectively. This is especially true for high consequence areas (HCA), where populated areas, ecological resources or water sources are in danger. PipePatrol Line Break Detection is a dedicated system to efficiently detect pipeline ruptures instantly, raise an alarm and initiate emergency pipeline shutdown procedures....

PipePatrol Tightness Monitoring Tightness Monitoring Small or gradual leaks are often not covered by standard systems, as pressure and temperature changes along the pipeline can mask small losses. The detection solutions possible are normally time and cost intensive. PipePatrol Tightness Monitoring is a method for the detection of gradual leaks using standard pressure and temperature instrumentation. This solution completely fulfils the requirements of TRFL 2017 and VdTÜV Bulletin 1051. It automatically creates a report according to these regulations and has been validated by independent...
