System Architecture & Typical Deployment Configuration
The WaveGuard® LDS System for a typical Negative-pressure Wave deployment is shown below. In this simple example two pressure sensors are placed at each end of the pipeline and one pressure sensor is placed in the middle to create 2 segments. The length of each segment could range from 10 to 25 km, based on the fluid type, pipeline parameters, and pipeline operating conditions. Gas pipelines typically require shorter segments for best detection performance.
Typical WaveGuard Leak Detection System Configuration
The two sensors at each end (A-B pair) are required in order to allow the LDS system to filter out noise arriving from outside the protected pipeline segments. Any field network can be used for the communication between the FSP units and the CC unit, and any communication network can be used for the communication between the CC, CMS, and the DCS / SCADA system.
Please note that this is just a typical configuration and the WaveGuard® LDS system can accommodate a pipeline of any length and topology .The WaveGuard® system is built using the best-in-class industrial hardware and software components.The following is a description of each major component in the WaveGuard® system.
