RÉSUMÉ

The facility for investigation of transient processes in turbine gas meters has been developed. The facility ensures instant switching of the turbine meter under test from one channel to another channel with different flow rate and measuring the meter response. The obtained results have been used for evaluating and predicting the meter dynamic errors at flow pulsation of any law. For this purpose, original combined computational-experimental method has been developed. The meter response and dynamic error have been evaluated as a function of frequency, amplitude, law of flow pulsation, and meter time constant of inertia.
