For continuous monitoring, Probability of Detection (PoD) can be framed as a function of time. Detection confidence grows with each measurement window. Here we explain how controlled-release testing and time segmentation translate PoD into Time-to-Detection (TtD) and contrast that with single-pass survey methods. For operators, this provides a practical way to set expectations for how quickly a continuous system will find different-sized events and why that matters for response.

Most LDAR methods capture only a snapshot, so they miss when an event starts, when it ends, and how long it lasts. Without that timeline, it can be challenging to quantify released volume, verify repairs, or determine whether the source is constant, intermittent, or tied to specific operations. Qube’s continuous monitoring provides 24/7 data that time-bounds emission events, enabling accurate volume estimates and confident repair verification.

The new methane rule enables operators to use approved advanced monitoring technologies, including continuous monitoring systems, to detect fugitive emissions. Qube’s platform meets and exceeds the technical requirements for using continuous monitoring systems under the rule.

Metal oxide sensors can drift from their calibrated baselines over time. But Qube’s remote auto-calibration process runs continuously and autonomously to identify potential drifts and correct itself to ensure consistent leak detection performance and data integrity.

Emission rates, emission durations, and wind speeds all vary, which can impact a continuous monitoring system’s probability of detection. Qube has developed a solution that optimizes device placements to assure the highest levels of detection and value for customers.
