These tests proved that our non-invasive, flexible CV system is well-suited to provide autonomous oversight for solvent exchange distillation processes. Overall, HeinSight2.0 was not impacted by the presence of additional visual elements (e.g., residue and solid) in monitoring and controlling the liquid level. While we demonstrated our system ability via a solvent exchange distillation, however, the underlying principle of controlling the liquid level can be exploited in other unit operations requiring liquid level oversight.
