摘要：
The present invention is a process for controlling a leak rate in a measuring system comprising an element under pressure, by allowing a leak rate proportional to the pressure from the system and in varying the leak rate in the manner as the pressure charge. The present invention allows lower high pressure to be applied to the element under pressure in order to obtain a given proportion of gas and therefore to reach the proportion of gas more rapidly by applying lower pressures to the element under pressure.
