Abstract

The step response of the turbine gas meter has been studied experimentally. Using the specially developed method the turbine gas meter rotation inertia time constant during step response has been evaluated. It has been found that the time constant depends not only on the final value of flow rate, but also on the current rotation frequency of the meter rotors. The results can be used for calculating the dynamic error of different types of tachometric meters with pulsing flow rate.
