Abstract: A meter electronics (100) for two or more meter assemblies (10a, 10b). The meter electronics (100) includes a processor (110) and one or more signal processors (120) communicatively coupled to the processor (110). The one or more signal processors (120) are configured to communicatively couple to a first meter assembly (10a) and a second meter assembly (10b). Accordingly, only one meter electronics can be employed to control the two or more meter assemblies, which may reduce the costs associated with employing two meter electronics.

Abstract: 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.

Abstract: A method of limiting a drive signal is provided. The method includes providing a drive signal for a meter assembly, wherein the meter assembly has a resonance frequency. The method also includes interrupting the drive signal after a first drive time-period, wherein the first drive time-period is based on an expected time for the drive signal to reach the resonance frequency.
