Abstract

Un método para la compensación de inversión en una bomba alternativa (12) para dispensar material fluido, teniendo la bomba (12) una válvula de retención (22), en el que dicha bomba (12) tiene un transductor de desplazamiento (14) para la medición del desplazamiento de la bomba, una válvula (12c) que controla la dirección de dicha bomba (12), un sensor (16) para detectar la posición de dicha válvula (12c) para determinar la inversión y un sensor de presión de salida, siendo el sensor de presión de salida un transductor de presión que lee la presión de fluido en la salida de la bomba (12), comprendiendo el método las etapas de: descartar cualquier desplazamiento y flujo imputado que se inicia cuando dicho sensor de posición (16) detecta la inversión; y reanudar considerando el desplazamiento cuando dicho sensor de presión de salida mide una presión predeterminada que corresponde a la reanudación del flujo real.
