Abstract: In the summer of 1997, Pacific Gas and Electric Company installed two 16 five-path ultrasonic gas meters. After three years of operation, it was discovered that a layer of compressor oil and dirt had accumulated on the meters interior walls and ultrasonic transducer faces. One of the meters along with its upstream spool piece were taken to a flow calibration lab where it tested 1.4% fast. After cleaning and other work, the meters basic calibration returned to within 0.3% of its original calibration which had been done at a different lab.
