Operating Procedures for the Portable Acoustic Monitoring Package (PAMP) 8th Quarterly Report. Report for March 31, 2004-June 30, 2004
The Portable Acoustic Monitoring Package (PAMP) has been designed to record and monitor acoustic signals in high pressure natural gas (NG) transmission lines. Of particular interest are the three acoustic signals associated with a pipeline fracture. The system is portable and can be used at all line pressures up to 1000 psig. The PAMP requires a shut-off valve equipped 1/2 inch NPT access port in the pipeline. It is fully functional over the typical pressure range found in the natural gas transmission pipelines in west Virginia, Virginia, Pennsylvania, and Ohio areas. With the use of the PAMP, a full spectrum of acoustic signals can be recorded and defined in terms of acoustic energy in decibels. To detect natural gas pipeline infringements and leaks, the acoustic energy generated inside the line is monitored with a sensitive pressure equalized microphone and a step function type transducer. The assembly is mounted on a 1000 psig pipe fitting tree called the PAMP. The electronics required to record, store and analyze the data are described in this report in the format of an operating manual.
