摘要：
The molecular weight of a pressurized flowing gas is determined by means of a vortex tube. The temperatures of the inlet gas to the tube and of its outlet hot and cold gas fractions are sensed by e.m.f.-producing temperature sensing means; the resulting e.m.f.'s are fed to a divider circuit which amplifies them, forms differential e.m.f.'s and a ratio of the differential e.m.f.'s, and converts the ratio to the molecular weight of the gas.
