Abstract
Un método y aparato para determinar una proporción de corrección de volumen para un gas (12), mediante la medición de la temperatura y la presión del gas de muestra (20), derivado desde una tubería (14), a medida que sufre una expansión controlada. El gas de muestra (20) fluye a través de una primera cámara (22), y un regulador de presión mecánico (24), donde se reduce la presión del gas de muestra (20). La proporción de decaimiento de presión del gas de muestra (20) se mide en la segunda cámara (26), y se compara con una proporción de decaimiento de presión del gas de referencia (31). La proporción de corrección de volumen se determina a partir del índice de cambio de presión en la primera cámara (22), la presión absoluta del gas de la tubería (12), y la temperatura absoluta del gas de la tubería (12). La proporción de corrección de volumen se utiliza para determinar la densidad de condición de flujo pf, a partir de una densidad de condición de base medida pb.
