FIELD: measuring equipment.
SUBSTANCE: measuring electronic equipment (20) is provided to determine the damping of the measuring unit (10) of the flow meter (5). Measuring electronic equipment (20) contains an interface (201) for receiving response vibration from the measuring unit (10), the response vibration contains a response to the excitation of the measuring unit (10) with almost resonant frequency, and a processing system (203) in connection with the interface (201). The processing system (203) is configured to receive a response vibration from the interface (201) and measure multiple response voltages (V) of the response vibration, the multiple response voltages (V) include at least one of one or more attenuation sites (430a, 530a-530f) and one or more enhancement sites (430b, 630a-630f). The processing system (203) is also configured to determine the cumulative damping-related value of the measuring unit (10) based on at least one of one or more attenuation sites (430a, 530a-530f) and one or more increase sites (430b, 630a-630f).
EFFECT: more correct determination of the damping characteristic.
