Guided Ultrasonics Ltd (GUL) has developed a permanently installed monitoring system, gPIMS®, and associated software tools to offer a fully comprehensive monitoring solution. This includes:
• The gPIMS® sensor, a pre-moulded environmentally sealed array of sensor elements that is bonded to pipe.
• The connection box, installed in an easily accessible location that can be up to 50m from the sensor position.
• The Wavemaker G4 Mini Collector instrument for data collection
• Data comparison tools built in to the WavePro™ software, allowing signal traces to be compared with each other in order to detect and track changes that have occurred to the pipe condition.
In many situations, the cost of accessing a pipe is much higher than the cost of inspection.
This cost can make continuous inspections with removable rings prohibitively expensive.
The environmentally robust gPIMS® range of sensors has been developed to be easily bonded to the pipe, sealed and then left in place.
A cable connects the gPIMS® sensor to a connection box that can be located in a convenient, easy to access location.
By performing repeat inspections and comparing the results to previous inspections, operators can monitor for any change in the condition of the pipe.
Frequent data collection significantly improves sensitivity and reduces false call rates compared to conventional guided wave testing.
