About Us

Monitoring Assets, Delivering Data, Bringing Control

Fluid Conservation Systems Inc. (FCS) is the North American industry leader in water loss recovery technology.

Established in 1978, the company relocated from its Austin, Texas roots to Milford, Ohio. The move was precipitated by the acquisition of FCS by Halma PLC. FCS is now part of Halma Water Management.

FCS was the first organization to patent leak correlation technology in the United States on April 11, 1978. Since that time, six generations of correlators have evolved leading to the TriCorr Touch Pro. Ongoing research and development, field application, field testing and extensive customer feedback has resulted in dramatic performance improvements since the initial patent.

Our primary focus for over 30 years has been proactive leak detection, however in the last few years we have expanded into new applications and sectors which include network distribution system monitoring, pressure modulation, sewer and storm water monitoring, river and flood monitoring. Our solutions have had a significant impact in helping our customers save time, effort, natural resources, energy and cost.

FCS staff pride themselves on customer support, service and responsiveness.
