Find a leak in less than 30 seconds before it is buried, without pressure by testing each pipe joint as it’s laid. An ultrasonic transmitter is used in coordination with an ultrasonic detector to find the leak. The detector converts inaudible ultrasonic signals into audible tones and amplifies them for ease of detection. By placing the transmitter on the inside of a pipe or test item, the signal will seek out and penetrate any hole in the pipe or joint. 541.548.1144

Fluid Conservation Systems
Deployed throughout a utility’s distribution system, Permalog + units attach magnetically to valves and use advanced algorithms to discern the acoustic signature of leaks from background noise. The units ‘wake up’ and listen during the night when ambient noise is at its lowest. If leak noise is detected, the unit reports this information via a two-way radio link, along with the approximate location of the leak, to a mobile unit that can then send a crew to pinpoint and repair the leak. 800.531.5465, www.fluidconservation.com

ADS
The Hykron Leak Listening System detects acoustic leak noise as it travels through water and the pipe wall -- it can be detected by listening at valves, hydrants or any available fitting on the pipe. Leak noise is detected in the pipe wall via a highly sensitive, built-in electronic sensor. Listening is conducted using the headphones with an extension rod and magnetic attachment. This entry-level system provides state-of-the-art electronics for improved signal to noise ratio. The Hykron’s low cost, sensitive acoustics, easy operation, durable construction and alkaline battery with easy field replacement make it an ideal tool for a water crew’s standard tool chest. It comes packaged in a convenient carry case with: handheld electronic sensor; amplifier with belt attachment; extension rods; magnet attachment; and high quality headphones. 800.633.7246, www.adsenv.com
