ABSTRACT:
A mass flow meter for a gas dispenser includes apparatus and method for determining specific heat ratio of the gas as a function of two pressure measurements in relation to a nozzle and for determining mass flow rate as a function of the specific heat ratio, the two pressure measurements in relation to the nozzle, and a density measurement of the gas.
