Abstract

Un sistema inyector de fluidos incluye al menos un inyector para presurizar y suministrar al menos un fluido desde al menos un depósito de fluido, al menos una sección de la trayectoria del fluido en comunicación fluida con al menos un inyector y que tiene un índice de refracción predeterminado, y un primer sensor proximal y un primer sensor distal dispuestos a lo largo de la al menos una sección de la trayectoria del fluido. Cada uno del primer sensor proximal y el primer sensor distal incluye un emisor configurado para emitir luz a través de la al menos una sección de la trayectoria del fluido, y un detector configurado para recibir la luz emitida a través de la al menos una sección de la trayectoria del fluido y generar una señal eléctrica basada en la luz recibida. El sistema inyector de fluidos incluye además al menos un procesador programado o configurado para determinar, en base a una diferencia en las señales eléctricas generadas por el primer sensor proximal y el primer sensor distal, al menos una propiedad de un contenido de la al menos una sección de la trayectoria del fluido.
