A method of limiting a current drawn by two or more meter assemblies (10a,10b) is provided. The method includes driving a first meter assembly (10a) with a first drive signal, comparing one or more operating parameters of the first meter assembly (10a) to an operating threshold, and driving a second meter assembly (10b) with a second drive signal based on the comparison to prevent a current drawn by the first meter assembly 10a) and the second meter assembly (10b) from exceeding a current threshold.
