Abstract

Un sistema para mejorar la medicion de presion del fluido en una válvula de control, el cual incluye colocar un acondicionador del flujo adyacente a y corriente arriba de, los canales de promedio del flujo, colocados en la entrada y salida de la válvula de control, desde los cuales los canales que promedian el fluido se dirigen a los dispositivos que miden la presion del fluido.
