Tomorrow Lab has developed an intelligent level-sensing fluid bag for medical applications, that will be capable of monitoring liquid levels inside flex containers (intravenous drug bags, drainage bags, etc.). Patented arrangement of capacitance sensors capable of performing accurate measurements of its contents and monitor liquid levels. Capacitance sensors include multiple conductive electrodes arranged in an interleaved or interdigitated pattern, oriented vertically, horizontally or angularly relative to an axis of the container. A connected digital converter converts the measured capacitance into digital data that becomes transported through the processor to the cloud.
