Dual-Sensing Water Level Controller
This newly revised version of the ELC-800 adds enhanced features and functionality with the same degree of accuracy you have come to know and expect. The 800r has an easy to program menu along with the ability to sense dangerously low water conditions and deactivate circulation pumps, protecting them from damage. Still taking advantage of proximity sensing technology, the ELC-800r stands apart from other water level controllers that use floats or introduce electrical currents into the water. The ELC technology is easily adapted to all bodies of water with the special sensing configurations depicted below.
Tri-Sensing Water Level Controller
The ELC-810 is an interactive, fully menu-driven, automated multi-level-sensing control system designed to maintain precise water levels for commercial swimming pools, spas, fountains, and water features. The ELC-810 uses proximity sensors to monitor the water level accurately and to automatically activate the auto water make-up control valve. It offers single, dual or tri-level sensing for normal, alternate, and high water levels; integral time delay sequence to avoid cycling due to wave action; and an adjustable feed alarm timer, which interrupts water flow in the event of a problem. In most cases the ELC-810 can be easily retrofitted to an existing pool, spa, fountain, spray ground, or other water feature.
