WLC D1 Water Level Controller is an automatic pump control device designed to monitor and manage water levels using the electrical conductivity principle. It is suitable for controlling water pump operation at two preset levels in overhead tanks, underground water tanks, and borewells. The unit continuously senses water presence through stainless steel probes and switches the pump relay automatically based on the installed sensor positions, helping prevent water overflow, dry running, and unnecessary manual operation. Built for reliable industrial and commercial use, WLC D1 supports a wide auxiliary supply range, making it adaptable to different electrical setups. It uses 3 stainless steel sensor prods, has adjustable trip settings based on tank level placement, and resets automatically after level changes. With fast trip response, low power consumption, and a compact ABS enclosure, the controller is suited for water management applications where consistent automation is required. The product is engineered for panel and 35 mm rail mounting, making installation easier in control panels and electrical cabinets. Its LED indication for power and relay status improves visibility during operation, while the robust electrical specifications and long operational life make it a practical choice for bulk procurement in building automation, water supply systems, and pump control installations.
