eREM is fitted with integrated laser scanning to allow plume flux to be deduced directly from a mass-balance calculation. The installed system is solar-powered, easy to install and align with pan / tilt platform, wireless, and provides real-time alarm notification to a remote operator. Data logging and analytics are performed in the cloud.

Scanning laser beam produces a flux plane to directly measures emission rates of methane plumes transported through this plane at ~1 Hz without plume modeling.
