Abstract

La inclinación de una cámara de goteo desde su eje vertical durante la administración de fluido puede tener efectos negativos en la precisión de los sistemas configurados para el conteo de gotas y/o para la medición volumétrica de gotas individuales que pasan a través de la cámara de goteo. Para abordar estos efectos negativos, de acuerdo con una modalidad de la presente descripción, un sistema de administración de fluido se acopla en un proceso de control de fluido que comprende determinar un parámetro de error, con base por lo menos en parte en una señal de inclinación, generando una condición de error, y ya sea mantener el flujo de fluido en el índice actual o detener el flujo de fluido.
