PWG II \u2013 Pulse generator<\/h1>

Effective cable search on plastic cables and other non-metallic pipes<\/h2>

The PWG II (Pulse Wave Generator) is designed for fast and accurate location of water pipes in conditions where traditional pipe locators cannot be used. The system enables the detection of plastic pipes, PE pipes and other non-metallic pipes without tracer wire or embedded metal parts.<\/p>

Using acoustic pulses sent through the water pipe, the pipe's route can be traced directly from the ground with a geophone or ground microphone. The system is particularly suitable for documenting unknown pipe routes, checking existing GIS data and locating pipes before excavation.<\/p>

How PWG II works<\/h2>

The PWG II is mounted directly to a hydrant, valve or internal installation via a quick-connect fitting. When activated, the system generates a series of acoustic pulses that propagate through the water and further along the pipe.<\/p>

The pulses are recorded on the ground surface using a geophone or FAST Aqua M-series listening equipment. By following the strength of the signal, the operator can quickly and accurately map the route of the line.<\/p>

Developed for difficult wiring routes<\/h2>
