Digital Automatic Water Level and Pump Controllers for Direct On Line DOL Pump Starters

The compatibility of our controller models (DOLS Digital) with Direct On Line (DOL) Three Phase ( 440 Volt ) motor starters provides a wonderful solution for efficiently managing water levels in both overhead tanks and underground reservoirs. The main function of this system involves continuous monitoring of water conditions with real-time updates displayed on LCD screens. Equipped with an auto-switching feature, it optimizes pump operations based on tank conditions, ensuring precise control and preventing water wastage. When the overhead tank reaches an empty state, the controller activates the pump while simultaneously displaying "TANK EMPTY" on the LCD screen. Subsequently, after reaching the maximum capacity indicated by "TANK FULL", the controller automatically stops the pump operation. This automated process streamlines water management, eliminating the need for manual intervention.

Dry Run Protection

Furthermore, the controller's functionality extends to Reservoirs (SUMP) as well. If the water level in the Reservoir drops below a certain threshold, the controller stops from initiating pump activation. Additionally, if the pump is already running when the water level becomes critically low, the controller halts its operation immediately and indicates "LOW SUMP" on the LCD. This feature is known as Dry Run Protection. It is crucial in preventing your pump burnout and ensuring your pump motor's longevity and reliability.

Power Protection

It features a 0.1Amp Glass Fuse, which provides additional protection for your pump motor. This safety feature prevents any electrical faults and protects this controller from excessive currents, strengthening system reliability. Additionally, it includes Surge Protection Technology to protect your controller from lightning and power surges, ensuring extra safety and longevity but it's true, In this case of any surge protection technology, exceptionally intense surges or direct lightning strikes might exceed the capability of the surge protection system, causing damage to the electronic equipment despite the protection in place.

Our Innovation

Our recent innovation involves the introduction of salt-free technology, a breakthrough designed to extend sensor lifespan. Despite initially utilizing stainless steel sensors, we identified the prevalent salt issue affecting many branded water level controllers. This prompted us to implement salt-free technology, effectively resolving salt or iron-related problems that commonly afflict such systems.

Summary

In conclusion, our controller model (DOLS Digital) for your DOL (440 Volts AC ) Three Phase Motor Starters offers a comprehensive and technologically advanced solution for monitoring and controlling your water levels and pump. The LCD display provides real-time water status updates, while the auto-switching feature optimizes your pump usage. The integration of Dry Run Protection, alongside Salt-Free Technology, not only safeguards the pump motor from potential damage but also extends the lifespan of the sensors, ensuring precision, reliability, and efficiency in water resource management.

We continually strive to innovate and cater to our customers' diverse needs. Our commitment remains steadfast in offering advanced, reliable, and customizable solutions that address the unique challenges faced in water management systems.
