Fluid Conservation Systems (FCS)

Fluid Conservation Systems (FCS), a Halma Plc company (FTSE 250) based in Milford, Ohio, has manufactured water and wastewater monitoring instruments for over 40 years, with more than 500,000 sensors deployed globally and 32,000-plus remote cellular sensors covering 7,000 miles of US drinking water infrastructure. FCS invented acoustic leak correlation technology and holds ISO 9001 and ISO 14001 registrations. In clean water distribution, the flagship PermaNET SU correlating cellular noise logger combines leak sensing with 4G LTE cellular communications in a single compact unit, earning the Environmental Protection Award and Build America Buy America qualification. The Permalog+ leak noise logger provides continuous monitoring with IP68 immersion rating, five-year battery life, and Aqualog noise trend analysis. The PermaNET TM GPS acoustic monitor targets trunk mains and plastic pipelines using hydrophone sensors. For pinpointing, the Tri-Corr Touch Pro leak correlator uses AFIS filtering with 55 combinations, and the DXmic Pro ground microphone delivers high-fidelity leak sound amplification. In wastewater monitoring, the RadarSens radar and ultrasonic level sensor provides ATEX Zone 0 certified non-contact level measurement with LTE-M connectivity. The SonicSens 3 ultrasonic level sensor offers IP68 waterproof construction with unwanted echo filtering, and the SpillSens digital float sensor delivers three-tier tilt-angle alert monitoring for CSO and sewer overflow compliance. Data platforms include PermaNET Web for leak correlation, DataGate 3 for hosted data management, and SpillGuard for real-time sewer network visualization.
