Abstract: This paper discusses routine maintenance issues relative to multipath ultrasonic meters used in natural gas for fiscal measurement. A basic review of an ultrasonic meters operation is presented to understand the typical parameters that are monitored. The meters diagnostic data, along with other operational parameters such as gas composition, pressure and temperature, can be used to help verify proper meter performance. Diagnostic information, obtained from the meter, can also be used to monitor gas velocity profiles and help predict unusual behavior due to obstructions, pipe wall contamination or other performance deteriorating conditions. Intelligent monitoring of the meters data will be discussed, and examples provided, to show how diagnostic data from an ultrasonic meter can be instrumental in determining a metering facilitys health.
