Speed and range benefits compared to camera insertion

An acoustic detection tool for use on natural gas distribution systems has been recently developed in conjunction with the Energy Innovation Centre. The system is ideally suited to identifying full and partial blockages, unexpected services, misbehaving valves or water pooling.

The tool is connected directly to a gas main and an acoustic signal is injected into the gas flow; microphones then record the acoustic reflection sequence and interpretation is performed using custom built Acoustek® software.

Speed and range are the two key advantages of the Acoustek® natural gas distribution tool when compared to camera insertion. Once connected, testing can be performed in less than 10 minutes at a range of between 200m and 500m either side of the connection on to the main; the exact range is dependent on pipe size and layout.

The Acoustek® gas distribution tool may be used as an alternative to, or in conjunction with, camera insertion. There is also future scope to adapt the equipment for use as a remote monitoring system.
