Flowmetrix Technical Services is an industry leader in providing water distribution studies including various leak detection strategies following best management practices. Using state-of-the-art leak sounding equipment and Leak Noise Correlators (LNC), form the foundation of an acoustic leak survey.

• Flowmetrix is able to address system design based on typical pipe size, materials and pressures providing a strategy most suitable for best leak finding results.

• Flowmetrix offers a traditional leak detection survey consisting of typical hydrant leak noise survey to locate potential leaks with leak noise correlation equipment to pinpoint such leaks. Although, this approach is more suitable to tight budget, realize potential leaks in metallic systems very well up to 12-inch in diameter.

• Flowmetrix also offers a more intense comprehensive leak detection survey consisting of traditional sounding techniques in addition to sounding each service connection and/or main line valve. Although, this technique is the most comprehensive and most costly will yield the best results in finding unreported leaks. Flowmetrix would advise our clients’ of better approaches to leak detection to best suit their financial dollar.


Flowmetrix Technical Services is an industry leader in providing water distribution studies including District Metering Areas (DMA). Using state-of-the-art flow meters, pressure instrumentation and data recording technologies (both stand-alone and wireless delivery services) are used to conduct these studies. Flowmetrix is able to utilize our data delivery service (web-hosted data server) infrastructure, to minimize field activities while maximizing available data. The host server is able to create upload “real-time” calculation or imaginary metering and/or flow/pressure system alarm notifications.

• Flowmetrix is capable of developing DMA zones, with intermediate zonal step-testing whether permanent in nature or suited for temporary studies.

• Using DMA studies to assist in real loss calculation, assisting with UARL statements, ROI statements related to varying leak detection strategies & efforts to locate and pinpoint leakage within the water distribution system.

• Use of DMA in conjunction with leak detection strategies to create system benchmark for lowest attainable level of leakage and economic level of leakage (ELL)

• Use for pilot studies to evaluate other physical leak detection strategies such as acoustic main/service leak detection surveys, correlation techniques, and/or helium leak detection programs.
