UK-based company JD7 has released the latest version of its internal tethered condition monitoring system - the LDS1000. JD7's tethered systems use a combination of acoustic and HD CCTV technology, and are launched through either a live fire hydrant or tapping point on the main. Leaks as small as 0.5 litres-per-hour can be detected says the company, and a sonde system allows the miniature head location to be identified from above ground.The system can also be used alongside a GPS locater to map out relevant sites and offer the customer a detailed computer aided design drawing. 'The idea of this equipment is that it goes into the main and it'll travel 1000m up the main and look within it for leaks,' explains Stuart Hamilton, Managing Director ofJD7.'Pipe material doesn't affect it, pressure doesn't affect it and mains diameter doesn't affect it.'
