Abstract

Un sistema de dosificación que suministra un fluido (A) a una mezcladora estática (1), comprendiendo dicho sistema: un depósito (2) que contiene dicho fluido (A) a una presión predeterminada y un elemento de presurización (B); un paso de fluido (3) que conecta dicha mezcladora (1) y dicho depósito (2); una balanza (5) que detecta un peso (PV_M) de dicho fluido (A) contenido en dicho depósito (2); una válvula de control (4) situada dentro de dicho paso de fluido (3) para controlar un caudal de dicho fluido (A) desde dicho depósito (2) hacia dicha mezcladora estática (1); un controlador (6), siendo dicho controlador un controlador (6) que puede operarse únicamente en modo de control automático o un controlador (6) que puede operarse tanto en dicho modo de control automático como en un modo de control manual, en donde: (a) en dicho modo de control automático, dicho controlador (6) recibe un caudal objetivo (SP_Q) de dicho fluido (A), y un caudal real (PV_Q) de dicho fluido (A), y emite a dicha válvula de control (4) una señal de control (MV_L) que controla la posición de válvula de dicha válvula de control (4) para ajustar el caudal; y (b) en dicho modo de control manual, dicho controlador (6) recibe una posición manual de válvula (MAN_L), introducida por un operario, como dicha señal de control (MV_L) para accionar dicha válvula de control (4); y un estimador de caudal (5c) que emite dicho caudal real (PV_Q) a dicho controlador (6), basado en dicho peso (PV_M) detectado por dicha balanza (5) en diferentes puntos temporales (t0, t1).
