Abstract: Automation first came into chart calculation in the early 30s with the advent of the McGaughy Integrator. Then some twenty years later, high speed computers began to provide impetus to research for faster means of chart interpretation. One of the answers to this challenge has been the Electroscanner chart scanner and computer system. This instrument scans the orifice meter chart with a revolving optical system, and an associated special purpose computer calculates the necessary integral of the square root of the product of the differential and static pressure levels. The Electroscanner computer calculates the square root of differential times pressure at 800 equally spaced points around the chart and then effects integration by summation of these 800 samples. The scanning and computation of a chart requires 10 seconds.
