QLM Technology develops instruments and software for measuring methane emissions. Its quantum lidar cameras scan sites to identify gas plumes and estimate the emissions associated with individual sources. The system combines a fixed monitoring instrument with software that displays emissions, their locations and measured rates. [Technology description](https://qlmtec.com/)
The company's software supports remote control of scanning, alerts when configured limits are exceeded, and reports covering individual assets or larger groups of sites. Operators can compare emissions with maintenance and other operational events. QLM targets uses in oil and gas infrastructure and wastewater operations, where finding the source of a leak is part of deciding what action to take.
