ABSTRACT OF THE DISCLOSURE The specification describes a compensating apparatus for use in conjunction with gas meters for effecting a standard volume register of gas without regard to density changes imposed by pressure and/or temperature in the course of transmission. A magnetic couple provides a drive input to a correction unit at a rate proportional to the operational rate of the meter. A sensing device sensitive to one of fluid pressure or temperature conditions is provided to produce a linear displacement motion correlated to a sensed condition change thereof in the fluid relative to a standard condition and an input device is provided to provide a constant position n setting correlated to a predeter- mined value of fluid pressure or temperature conditions for the other of the one condition to which the sensing device is sensitive. A multiplier device separately receives both the sensing device displacement motion and the constant value of the input device to produce an integrated output displacement motion correlated to the multiplication product thereof.
