Advancing leak detection on rising sewer mains
In Q2, Atmos supported the monitoring of a UK customer’s critical rising sewer main using Atmos Eclipse and the latest Atmos 4G Sentinel models. The system applies single-ended leak detection techniques to track potential failures along the sewer pipeline.
Closely analyzing the pressure data, we reported several significant leak events that align with recently observed flooding incidents:
Alongside these main events, many short-duration leaks, most under one minute, have also been detected. These brief anomalies are common in sewer pipelines, where debris may temporarily seal leak points, highlighting the need for continuous, high sensitivity monitoring.
On the downstream end of another UK pipeline, Atmos recently installed a 4G Atmos Sentinel (see Figure 1) to enhance detection and location capabilities.
Figure 1: Atmos Sentinel 4G installed on a process connection within the customer’s chamber. The 4G antenna has been mounted directly onto the unit and even when the large metal cover is in place, we have been receiving data via 4G.
Notably, Atmos Sentinel’s 4G antenna continues to transmit data reliably even when housed in a chamber beneath a heavy metal cover, underscoring the robustness of the solution.
Atmos continues to expand its water monitoring solutions in the UK and across the world, helping clients detect leaks faster, minimize flooding risk and improve pipeline resilience

Pipeline analytics help uncover customer’s hidden pressure anomaly
Atmos’ pipeline analytics platform helped a North American operator detect and resolve a recurring pressure anomaly. During a routine review, the system flagged a sharp increase in static alarms on two detection units. While initial investigations revealed oscillating pressure, no corresponding system tag was present, leaving the root cause unclear.
Figure 2: The increase in static alarms
Working closely with the client’s facility operations team, the issue was traced to a previously overlooked thermal pressure safety valve on a branched line. Rising daytime temperatures were causing thermal expansion in stagnant sections of pipework, triggering pressure relief events that aligned with the observed alarms.
Thanks to detailed alarm data and actionable insights, the operator was able to identify the anomaly early, understand the cause and take corrective action, avoiding unnecessary alarm fatigue and improving system visibility.
This pipeline analytics platform integrates with Atmos products as an additional service, periodically retrieving information about the status of all leak detection units and providing a summary of network activity such as leak alarms, operational status, uptime and more.

Detecting pigging-related flow imbalance and adapting to reduce false alarms
Last quarter, Atmos Wave demonstrated its advanced sensitivity and reliability during a standard pigging operation on a long distance crude oil pipeline in West Africa. While operators were filling the pig receiver, positioned between the inlet and outlet flow meters, the system detected a sudden flow imbalance and triggered a leak alarm.
Although no actual leak occurred, the temporary discrepancy (see Figure 2), caused by the pig receiving process, was enough to trigger Atmos Wave’s alert. The system identified what appeared to be a ~1% leak within minutes, despite a 6% discrepancy between the flow meters and a separation of over 200 km between them. This performance is a direct result of careful tuning and the system’s ability to interpret nuanced operational behaviors.

The client praised the system’s responsiveness and accuracy, particularly in its ability to detect and differentiate simulated leak conditions from regular operational activity.
Adapting to reduce false alarms
As part of the testing process, the system’s adaptive learning capability was also evaluated. This feature automatically adjusts sensitivity based on known pipeline behaviors, such as pigging, reducing the likelihood of false alarms. Before applying this feature, the Kappa value (a leak confidence indicator) was nearing the alert threshold. After enabling the learning function, the Kappa value dropped closer to zero, reflecting a more stable system response and enhancing long-term reliability.
