Why does SF6 electrical equipment use density meters to monitor gas leaks?

Density refers to the mass ρ=m/V(kg/m^3) per unit volume of a specific substance under certain conditions, for SF6 electrical equipment in a chamber gas is sealed in a fixed and unchanged container, if there is no leakage, the gas mass in the chamber will not change, the gas density will not change, such as
If the gas chamber is lowered, it indicates that the gas chamber is leaking. Since the size of the density is independent of the change in temperature, a density meter can be used to monitor gas leaks.
