ABSTRACT:
To obtain better accuracy, it is known to modify the mechanical metered volume reading of the flow through a gas pipeline according to the gas laws, which incorporate the pressure and temperature parameters of the gas. The present invention samples those parameters with analog sensors and inputs them into an analog to digital converter. The digital output from the converter is employed to obtain a more accurate digital volume reading.
