THE PIPELINE PROTECTION METHOD OF CHOICE
Ensuring pipeline integrity, immediate leakage detection and risk mitigation
Pipelines are long underground structures, subject to sophisticated pipeline theft actions, malicious interference or unauthorized construction work. AP Sensing's solution for pipelines provides the capabilities to monitor the entire downstream process 24/7. Utilizing the newest Distributed Temperature Sensing (DTS) and Distributed Acoustic Sensing (DAS)/ Distributed Vibration Sensing (DVS) technologies, our pipeline monitoring solution is an integrated fusion of the newest sensing hardware and detection algorithms, plus presentation and interface software.
Our AP Sensing pipeline monitoring technologies combine to provide multiple benefits, such as leakage detection, flow assurance and third-party interference (TPI) protection - all while minimizing false alarms and maximizing detection probability. Our solutions detects even pin-hole leaks and deliver alarms quickly, while locating the event to within a few meters of its position. TPI events can be identified and classified in real time to raise an alarm only if the event is a threat to your infrastructure. By enabling the process control of active heating, pipeline flow assurance is maintained, which also optimizes energy usage.
DISTRIBUTED TEMPERATURE & ACOUSTIC SENSING
AP Sensing's monitoring solution converts a standard optical fiber into a continuous multi-parameter sensor. Our DTS detects pipeline leaks by analyzing the temperature and precisely localizing any hot spot or cold spot. It also identifies thermal anomalies such as the cool effect of an escaping gas, or manages active heating processes such as in a sulfur pipeline. DAS/DVS detects leaks by noise and vibrations, as well as temperature changes (DTGS) and negative pressure waves generated by the leak. DAS/DVS is also used to detect defined third-party activities, whether accidental or deliberate, such as digging close to a pipeline.
SMARTVISION™
AP Sensing's SmartVision™ management suite shows the condition of your pipeline at a glance, controlled by an easy-to-use graphical interface. It seamlessly integrates many DAS, DTS, CCTV and other sensors into a single platform. Pipeline layouts are mapped and color-coded to show the measured pipeline temperatures, as well as instantaneous changes in acoustic energy. Temperature graphics and hotspot tables are readily available. Sections of the cable route can be individually defined for flexible alarm levels and types.
FEATURES
Our solutions monitor key pipeline features, including:
- Leak detection/location of gases, water, liquid hydrocarbons, LNG, LGP and multiphase pipelines

Digitization is the driver for quality, capacity and efficient railway operation for DB Netz AG. Fiber Optic Sensing is an outstanding technology that enables the improval of infrastructure capabilities at lightspeed compared to other solutions using existing cable infrastructure. AP Sensing is taking FOS-based railway monitoring to the next level with their true phase-based system and the extensive use of AI. We’re happy to work in collaboration with AP Sensing’s responsive and innovative team, helping us to get projects moving and getting FOS integrated in the daily railway operation.
AP Sensing's support team has been a fantastic resource for us over the years. They have helped us with system development and implementation planning, and they are always quick to respond to our technical queries with competent advice and helpful tips.
For me AP Sensing is the forerunner for distributed optical temperature sensing. You can see in their solutions a combination of experience and creativity -- an intuitive design that works just as you'd expect, yet they aren't afraid to think out of the box, or provide a customized solution. They carry on their HP/Agilent heritage and continue to develop and advance, while remaining true to their core values of quality and reliability.
When I think of AP Sensing the first thing I think of is reliability. We completely trust and rely on their performance specifications and I know that their technical support team is dedicated and passionate about solving any problems that might come up.
Knowing the technology and market, it is evident to me that AP Sensing is the forerunner in distributed optical sensing. Their solutions reflect a combination of experience and creativity. Experience comes from their HP/Agilent heritage, the leader in test and measurement equipment, with decades of experience in developing and manufacturing extremely reliable and high quality products. The creativity comes from their passion and commitment to solving real customer problems.
When you do business with AP Sensing you get the feeling that you are working together as partners, because they listen to you and understand the challenges of your day-to-day operations. Communication with AP Sensing is always professional and it's obvious that they have the experience and the technical know-how to answer our queries.
AP Sensing's DTS is simply the best fit. We apply it together with ConveySafe in our coal power plants to protect our conveyors. The systems are rugged and completely reliable, need very little power, and can be seamlessly integrated into customer SCADA environments. Best of all, you don't just buy a box from them and that's it -- their post-sales support is outstanding.
The SIL-2 (Safety Integrity Level) rating that AP Sensing has achieved on its DTS gives us the confidence that their solution is going to work as planned, day in and day out, in high-risk environments. Our LNG terminal operators sleep better at night knowing that our assets are protected and security standards are met.
My AP Sensing regional customer support is fantastic: competent, thorough and quick to get back to me. They have been a key player in our complex pipeline projects over the years, and they truly offer through-life product support, from installation and commissioning to training.
