Waterline Controls® has been involved in designing and developing maintenance & hassle-free electronic water level controls for over twenty-five years. The applications range from residential swimming pools and fountains to commercial cooling towers, boilers, fire protection tanks, and sump controls. Our primary goal is to unify all wet environment points in a commercial facility and ensure an ease of access. We do this by developing stand alone controls for individual applications that link back to the building management system. Our controls offer a user friendly LED panel, and a color coded wiring system for easy installation. By using one core technology, Waterline Controls, you can See It! Control It! The WLC Series may look like the competition but the unit is revolutionary in its design. The WLC Series is perfect in any application where water level management is important such as cooling tower basins and water holding tanks for cooling towers. It uses a microprocessor that monitors all probes for correct operation and then provides the corresponding outputs to drive power relays, the Building Automation System, and a visual indication of the operational status. The Modular construction, color coded wiring and a self-test feature insure user-friendly operation. By using a very low voltage and current, WLC Series sensors never foul, pit or degrade. So when we say "Never Replace A Water Level Controller Again" we mean it!
