METHOD FOR DETERMINING CUBIC CAPACITY OF NONPRESSURETIGHT GAS-FILLED CONTAINER Russian patent published in 1994 - IPC

FIELD: measuring equipment. SUBSTANCE: container is filled with a certain fixed amount of indicator gas. Before introduction, this gas is constantly mixed in the container throughout the process of measuring, the background concentration of indicator gas is measured in container by the value of lower indication limit of the measuring means. The amount of indicator gas is determined by approximate cubic capacity of the container and maximum concentration is calculated by momentary introduction into the container of the entire amount of indicator gas without losses. The true cubic capacity of the container is found in processing the measurement results by the formula submitted in the description. EFFECT: higher efficiency. 2 dwg
