ABSTRACT:
A method of determining the mass flow of a fluid comprising measuring a plurality of parameters comprising the pressure P, the temperature T and the density .rho. of the fluid, determining the specific gravity G of the fluid from the said parameters, and using the measured density .rho. together with a further parameter which varies with the volumetric flow to evaluate the mass flow of the fluid only if the so-determined value of G is within a given range of values.
