| 摘要 | PURPOSE:To obtain a correcting method for a section of an uniform measuring receptacle, by a method wherein a minute increase or decrease amount in liquid in a receptacle is divided by an increase or decrease in pressure of a liquid column, and a correction body is cut or added according to the dividing results. CONSTITUTION:Water flow paths 3 and 2 and a pressure measuring path 5, in which a differential pressure converter 6 is situated in the middle of the path 5, are installed in a receptacle 1, and a correction body 4 having an uniform section is located in the receptacle 1. After the receptacle 1 is filled with fluid through an inlet path 2, the inlet path 2 is closed. An inlet path 3 is then opened, and an approximately constant amount of liquid is flowed out intermittently. With this a decreasing height of a liquid column, which is due to a decrease amount in output of the differential pressure converter, is measured. After liquid in the receptacle 1 flows out, an intermittent flow amount is divided by the decreasing height of the liquid column, and the spherical surface of the correction body 4 is modified by cutting and adding according to the division results to change the section. This causes the uniformalization of the section of the receptacle 1 when the correction body 4 is set into a condition to be placed in the receptacle 1. | ||||||
