Abstract
An electrical isolation system for monitoring liquid flow rate from pumping equipment housed within a confined enclosure, wherein the flow rate signals are developed into optical signals which are conveyed via fiber optic cables from within the enclosure to control modules outside the enclosure. The control for operating the system may thereby be wholly electrically isolated from the pumping equipment.
