This paper highlights several rotary meter performance characteristics. These characteristics profile a rotary meter’s capabilities in a wide array of applications from production to transmission, and distribution. Most of the characteristics have minimum standards adopted by agencies like AGA or ASTM. I’ll identify these standards, and incorporate them?where applicable?into my paper. In discussing these characteristics, I hope to give the reader a better understanding of the capabilities of rotary meters, and how the gas industry assesses these characteristics. Here’s the performance characteristics I’ll discuss: • Rangeability • Start Rate • Stop Rate • Stating & Running Differential • Accuracy
