Abstract

A magnetic couple provides a drive input to the correction unit at a rate proportional to the operational rate of the meter. Separate temp. and pressure sensitive mechanisms exposed to the gas flow each provide a linear displacement proportional to changes in their absolute condition. Respective displacement of each sensor is supplied independently to a dual input single output multiplying mechanism from which an integrated output serves to position a limiting cam in angular correlation therewith. Position of the cam effectively modifies the drive input from the magnetic couple through a crank arrangement that drives the corrected register at a rate correlated to the integrated function of absolute pressure and temp. of the metered gas.
