New Developments in Thermal Dispersion Mass Flow Meters

Presented at the American Gas Association Operations Conference

This by Sierra founder, Dr. John G. Olin,paper describes a newly developed microprocessor-based thermal dispersion mass flow meter that uses four temperature sensing elements in its flow sensor instead of the traditional two elements and automatically manages changes in gas selection, gas temperature, gas pressure, and outside temperature. This new mass flow meter is ideally suited for apportionment applications in natural gas distribution systems.
