PROBLEM TO BE SOLVED: To dramatically improve the accuracy in flow rate measurement by an ROR (rate of rise) system by easily obtaining compression coefficient as characteristics of a fluid.SOLUTION: The fluid characteristics measurement system includes: a container 1 which has a constant capacity; a flow rate controller 2 connected to the container 1 so as to introduce a fluid thereto at a constant flow rate; and an information processing device 5 that calculates a compression coefficient according to the pressure of the fluid based on each time change of the pressure in the container 1 when fluid is introduced into the container 1 at the same flow rate by the flow rate controller 2 under the two conditions in which the pressure in the container 1 is different.SELECTED DRAWING: Figure 2 【課題】流体の特性である圧縮係数を容易に求めることができるようにし、ＲＯＲシステム等による流量測定精度を飛躍的に向上させる。【解決手段】一定容量を有する容器１と、該容器１に一定流量で流体を導入可能に接続された流量制御器２と、前記容器１内の圧力が異なる２つの状況下において、前記流量制御器２によって互いに等しい流量で該容器１に流体を導入した際の、該容器１内の圧力の各時間変化に基づいて当該流体の圧力に応じた圧縮係数を算出する情報処理装置５とを具備するようにした。【選択図】図２
