Never Replace Water Level Controls, Liquid Level Sensors, or Float Switches again!

After more than 20 years revolutionizing the recreational water industry with our low-maintenance water level controls and supremely accurate liquid level sensors and level switches, Waterline Controls is now applying its design knowledge, manufacturing experience and customer service expertise to the electronic level switch for commercial and industrial applications where water level management is critical like Boiler Installations, Cooling Tower Basins, Fire Protection Tanks, Sump Areas and Well Water Tanks. The Waterline Controls unit comes as a kit with an electronic water level controller, sensor and mounting assemblies. They can be customized to fit your specific needs.
Our modular liquid level sensors guarantee trouble-free level control. These water level controls will eliminate the hassle and frustration normally associated with existing float switches, ultrasonic or other electric level controls. All our models are backed by a 100% Satisfaction Guarantee - IF IT DOESN"T WORK WE WILL TAKE IT BACK - PERIOD.
The liquid level sensors we use completely eliminate the chance of injury due to electrical shock during installation or maintenance, and are Listed to UL508 Standard by ETL. There is no need for calibration unlike a great deal of our competitors because it is designed for use in water. All of our liquid level controls and liquid level sensors are assembled right here in the U.S.A. where we monitor every step of the manufacturing process. That gives us the confidence to guarantee your satisfaction. Once you experience the accuracy and reliability of our water level sensor and control unit in the field, you'll be convinced that their easy installation, superior performance and long-term durability compared to float switches make them the right choice for any situation.

The categories listed above are but a few of the ways our water level controllers can be used. Virtually any industry will have to store significant volumes of water for either their production operations or various plant management systems. Many of those industries are using seriously out-dated technology and making due with components that are expensive and difficult to maintain. What Waterline Controls offers is a complete, simple, and reliable solid state electronic level control system, following a modular design that allows for easy maintenance, while insuring that all your components will happily work together. When you start mixing components from third party manufacturers (a float switch, extra level switch, liquid level sensor), mysterious problems have a habit of cropping up. Save yourself a huge headache, and go with the complete system that has a 100% guarantee, backed by over 20 years of experience in the field.
