Abstract

A vibrating fluid density transducer 10 provides a gas density measurement D, used in conjunction with a volume flowmeter signal frequency fB, to meter the mass of gas fed through a pipeline. D is subject to errors dependent upon the velocity of sound C in the gas. The errors are corrected to yield the actual density Da by application of a correcting formula (block 18) in which C is introduced by calculation (block 17) from a measurement of gas pressure P by a transducer P. The value of C may alternatively be measured directly, computed from a measurement of specific gravity or in the case of a liquid, be inferred from D or be preset. <IMAGE>
