DEVICE FOR MEASURING THE VOLUME OF GAS EMANATIONS

摘要

This device for measuring the volume of emissions of gas comprises, connected by pipes (5, 6, 7) to a cell (2) in which the gas emitting specimen (1) is immersed, a flexible jacket (4), contained in another enclosure (9) and which receives the gas emitted. The inside of the jacket (4) and that of the enclosure (9) remain at ambient pressure thanks to an outlet duct (13). The volume of gas emitted is measured indirectly by a positive displacement meter (16) placed on the duct (13). Measurement defects caused by variations in pressure in the emission volume or by the impossibility of calibrating the meter for the gas emitted are avoided, and the emitted gas is confined and can be sampled without difficulty.
