The electronics semi-conductor revolution has touched every industry and home in the nation. The gas industry is no exception. Sophisticated gas measurement instrumentation has been with us for several decades now, but only in the last 10 years or so has it really begun to boom. First marketed were the flow computers dedicated to orifice meter measurement; but with steadily decreasing manufacturing costs, electronic instrumentation is now moving into the area of base volume, pressure and temperature correction previously handled almost solely by mechanical integrating instruments. This paper takes a brief look at some of the features of the newcomers on the market and how they stack up against the old standby mechanical base volume/pressure/temperature correctors.
