Flow pulsation in the turbine gas meters cause dynamic error, amounting to tens of percent. So far, the problem has been studied only for pulsations by rarely encountered in practice, simple laws. To calculate the meters' response and dynamic error at pulsing by any arbitrary law the new method has been developed and implemented. It is based on the concept of meters' inertia time constant as the only characteristic of transitional processes of rotation. For the first time the information on the turbine meter behavior under sign alternating pulsation conditions, when the instantaneous flow periodically changes direction on the op-posed one has been obtained. The results has been analyzed and generalized. and compared with the experimental ones obtained with a specially delivered facility. Gas pulsations parameters and the dynamic error have been researched in one of the thermal power plants. The measures have been proposed to reduce pulsing and errors to the acceptable values to avoid vibrations.
