A detector to pinpoint natural gas leaks in medium and high pressure distribution systems has been developed through the prototype stage. The device can detect acoustic emissions from leaking gas in the 2-5 KHz range. The actual leak pinpointing sensor, which is moved from one position to another above the pipe until the leak site is pinpointed, and a background noise monitor, offset from the pipe area, that is used to substract background noise from the signal developed by the leak pinpointing sensor. The prototype device is handportable, rugged, and low in cost, yet sensitive and easy to use in the field, as demonstrated with preliminary fields tests. (Kursetz)
