What is a sonde? A sonde is a small usually waterproof device that generates a RF signal in the form of a pulse. This pulse is able to be synchronised with by a receiver and buy pulling or pushing it into a pipe or conduit the asset can be found.
Rodding is placing a conductive wire into a pipe to act as a conductor for a signal.
The Sonde and Rodding techniques are used when pipes or conduits the assets are running in are not able to carry a signal such as;
• PVC pipes
• AC Pipes (Asbestos pipes)
• VC Pipes (Vitrified Clay Pipes)
• Concrete pipes
• Any non-conductive pipe
An example of services that may require sonde and rodding include;
Any plastic or cement pipes.
What if there is no access to the inside of these pipes or cables?
There are still more options.
