Abstract
A new approach to measuring mass flow rate using critical nozzles is proposed. The novelty of the approach lies in the fact that the laws of conservation (of mass, energy and momentum) in the one-dimensional gas flow are matched and the dependence of the thermal characteristics of an actual gas (the adiabatic exponent and the compressibility) on the static pressure and the temperature in the gas flow is taken into account. The VNIIMS procedure and algorithm are presented and are illustrated using a specific example.
