Abstract: This paper discusses advanced diagnostic features of gas ultrasonic meters (USM), and how capabilities built into todays electronics can identify problems that may have gone undetected in the past. It primarily discusses fiscal - quality, multi -path USMs and does not cover issues that may be dif ferent with non -fiscal meters as they are o ften single path designs . Although USMs basically work the same, the diagnost ics for each manufacturer does vary. All brands provide basic features as discussed in A GA 9 Ref 1. However, some provide more advanced features that can be used to help identify issues s uch as blocked flow conditioners and gas compositio nal errors. This paper focuses on the Westinghouse and British Gas configuration s ( both being chordal design s) and the information presented here may or may not be applic able to other path de signs .
