COMMISIONING & OPERATION
The commissioning takes place after covering.
When connected to the sensing element the system automatically aquires: the GPS coordinates; the exact length of the SE; and a baseline measurement which is stored in a database & associated with an ID chip contained within the buried sensing element.
Either during commissioning or at some point in the future it is recommended that leak simulation tests are carried out. The efficacy of the system is tested & providing the highest confidence. The tests can be achieved using secret valves, soaker pits, or other means to simulate the presence of leakage.
Operation of the system is automated making it simple and fast, each time a transceiver is connected to a sensing element it performs a preprogrammed routine.
ID & GPS position of the sensing element are automatically acquired so that the Leak Location Practitioner does not need to record this information manually. Similarly baseline and any previous measurements are automatically compared, with leak positioning information calculated by linear distance from the GPS position of the measuring station. The average daily testing rate for field testing is around 20km per day.
