By implementing a monitoring system to a fluid meter set, the meter set can be monitored for abnormalities including fluid leaks or other system failures as well as gas blend or gas density. A monitoring system that uses sensors such as vibration sensors can detect fluid leaks or other system failures based on abnormal conditions such as vibrations of the meter set. Sensors may be positioned at various locations along the meter set where leakage of fluids or other system failures may be possible. Sensory information detected by sensors are communicated to processing or control unit which can trigger an alarm signaling unit alerting of a potential fluid leak. Such a system of monitoring the integrity of a fluid meter set can help to quickly identify and respond to a fluid leak without necessarily relying on visual or olfactory cues associated with the fluid being leaked.
