GasCam can assist maintenance personnel by accurately locating blockages, water infiltration, cracked or broken mains, undocumented valves and service taps, and unauthorized service taps. It can also be used to inspect tanks or other confined space vessels, without risk to personnel. Certified intrinsically safe to stringent Class I, Division I, Group D standards, GasCam, can perform live inspections in 2- to 12-inch mains operating at up to 60 psig and at distances up to 480 feet from a single entry point. Entry can be either with a slight interruption of gas or no-blow using the Aries’ NB-60 Launching System. 800.234.7205,

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,

Find a leak in less than 30 seconds before it is buried, without pressure by testing each pipe joint as it is 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
