This is not something we have measured. Different models may operated/behave differently and at different frequencies. Do you happen to know the frequencies they use for data transmission? Most likely the meters are producing microsurge electrical pollution (dirty electricity/emi) as they most likely use a switch mode power supply. The filters will help with that issue.
