Waterline Controls’ solid-state, all-electronic, USA-made water level controllers for Fire Protection Storage Tanks provide the ease of installation and operation, accuracy and reliability you need for the mission-critical operation in these applications.

All of our controllers meet NFPA 22 and NFPA 72 requirements and can be customized to meet any local Fire Marshall guidelines. Our controllers are approved for use under some of the most stringent requirements established by authorities having jurisdiction, including Los Angeles County and the city of Seattle. Our control panels meet all NEMA 4x requirements for indoor and outdoor usage.

Easy Installation – Installs in less time than you think, saving time and labor costs. Our microprocessor-driven controllers are designed to easily integrate with existing Fire Panels.

Easy Operation – Our “always on” LED Indicator Lights quickly show you at a glance the current status of all functions. Five of our models include automatic precision fill control on demand. The built-in High/Low Alarms in 8 of our models will automatically alert you if any necessary action is required.

Easiest Maintenance – With its modular design, you’ll only replace individual components, not the entire controller. Our long-life stainless steel sensors/probes means no fouling, plating, degradation or continual replacement regardless of water quality. And our Superior Tech Support means you’ll talk directly with our highly trained, knowledgeable, USA tech support people who understand your needs & challenges in the field.

Most Accurate – Our controllers are designed to compensate for wave action and will maintain water levels to within 1/8” of operating range.

Most Reliable – Our controllers are designed to ensure a minimum 15-Year duty cycle with a 99% uptime rate and are backed by a 5-Year Limited Warranty. Your satisfaction is ALWAYS guaranteed.

Customizable – Each of our shock-proof, stainless steel sensors/rods can be customized to any length (to over 50 feet!). Our unique Paragon Valve configuration can be easily integrated into our controllers for added protection in case of power loss during a fire or other electrical interruption. A temperature sensor is optional on all of our controller models. Some of our models allow for the output of both temperature level requirements for heater control and alarms.
