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.

A method of limiting a drive signal, the method comprising:
- providing a drive signal for a meter assembly, wherein the meter assembly has a resonance frequency;
- and
- 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.
A meter electronics (100) for limiting a drive signal, the meter electronics (100) comprising:
- a processor (110);
- and
- one or more signal processors (120) communicatively coupled to the processor (110), wherein the one or more signal processors (120) are configured to:
- provide a drive signal for a meter assembly (10a, 10b), wherein the meter assembly (10a, 10b) has a resonance frequency;
- and
- interrupt the drive signal after a first drive time-period (Ta), wherein the first drive time-period (Ta) is based on an expected time for the drive signal to reach the resonance frequency.
A dual vibratory sensor system (5) for limiting a drive signal, the dual vibratory sensor system (5) comprising:
- a first meter assembly (10a);
- and
- a meter electronics (100) coupled to the first meter assembly (10a), the meter electronics (100) being configured to:
- provide a drive signal for the first meter assembly (10a), wherein the first meter assembly (10a) has a resonance frequency;
- and
- interrupt the drive signal after a first drive time-period (Ta), wherein the first drive time-period (Ta) is based on an expected time for the drive signal to reach the resonance frequency.
