Abstract
A calibration system for a mechanical gas volume corrector which has a first shaft turned at a rate corresponding to the otherwise uncorrected volumetric flow rate through the meter, a second shaft, a variable ratio transmission coupled between the first and second shafts, and a mechanism for altering the ratio of the transmission in response to changes of a physical condition of the gas. The calibration system includes an arrangement for applying a representation of a reference state of the physical condition to the ratio altering mechanism, and indicator for indicating a fixed number of revolutions of one of the shafts, an arrangement for determining the number of revolutions of the other of the shafts corresponding to the fixed number of revolutions of the one shaft, and a calculator for determining and displaying the ratio of the other shaft revolution number to the fixed number. The calibration system also includes an adjustment mechanism for changing the zero setting and the span (or gain) of the ratio altering mechanism.
