Abstract: In the 1930s, when more and more utilities began to sell large volumes of gas at elevated pressures, i.e. at pressures above inches water column, it became apparent that devices were needed which, clock or meter driven, would correct measured volumes for pressure and temperature. The first such instrument was introduced by the American Meter Company and soon several other companies introduced similar instruments, These were essentially mechanical calculators of which certain inputs were automatically adjusted as the pressure or temperature fluctuated. Their design has remained virtually unchanged through the years and a great many of these instruments are still in use today.
