Rotary positive displacement gas meters have been in use for more than 75 years. In that time, they have become the preferred method of measurement for industrial and commercial gas loads. The rotary meter is designed to measure gas with a very high degree of accuracy and reliability over time. They also offer the unique-to-rotary-meters differential testing capability, which reduces the need to shut down for testing and lowers the whole-life cost of ownership. Advancements in technology continue to improve meter performance making rotary gas meters a vital element in gas measurement today.
