Why Choose Us


The iSeries is the only tank monitor tested and approved by the United States Coast Guard. It has patented technology with Level Alert™ and is NMMA Certified using ABYC standards. Other tank probes often become corroded or clogged with materials. This send false signals to the panel. Sensors on the iSeries system mount externally and actually read through the tank wall.

As the only manufacturer of tank monitoring systems approved by the U.S. Coast Guard, we ensure our clients receive top-tier safety and performance. We are dedicated to delivering durable, American-made tank monitoring systems that cater to both individual aftermarket needs and large-scale OEM requirements. When you choose us, you are investing in decades of refined engineering and unparalleled customer support.

  • Where can I find the best tank monitoring systems for boats and RVs in the Willamette Valley?

    If you are searching for premium tank monitoring systems in the Willamette Valley, we are your premier local source. We offer the highly acclaimed iSeries tank monitor, which is uniquely designed to provide highly accurate readings for fresh, waste, and fuel tanks without invasive drilling. Our specialized capacitive sensing technology eliminates the issues of traditional probe sensors, such as corrosion and false readings. Whether you are upgrading your personal recreational vehicle or retrofitting a fleet of marine vessels, we provide the most reliable, locally supported systems to keep your journeys safe and worry-free.

  • How do non-invasive capacitive tank monitors prevent false readings and corrosion?

    Traditional tank sensors rely on probes that come into direct contact with liquid, leading to rapid corrosion, debris buildup, and highly inaccurate readings. We solve this problem by utilizing advanced capacitive sensing technology. Our external sensors are applied to the outside of your plastic holding tanks, allowing them to read fluid levels directly through the tank walls. Because our components never touch the liquid inside, they are completely immune to the clogging and chemical degradation that ruin standard monitors. This non-invasive design ensures your RV or boat displays consistently accurate, maintenance-free level readings for years to come.

  • What are the safety standards for marine holding tank monitors?

    Safety standards for marine electronics are incredibly strict to prevent electrical hazards and fuel-system failures. For ultimate peace of mind, marine tank monitors should ideally meet American Boat and Yacht Council standards and hold National Marine Manufacturers Association certification. We are proud that our iSeries monitoring systems are currently the only tank monitors tested and approved by the United States Coast Guard. This prestigious designation ensures that our products meet the highest rigorous safety protocols for marine environments, making them the safest and most reliable choice for monitoring fresh water, waste, and fuel tanks on any vessel.

  • Can your tank monitoring systems be customized for manufacturing and OEM partners?

    Yes, we specialize in providing tailored solutions for original equipment manufacturers. We understand that boat and RV builders have unique specifications, which is why we offer comprehensive OEM customization options. Our experienced engineering team can design branded display panels that seamlessly match your interior aesthetics and implement custom software programming to fit your specific tank sizes and layouts. Fully manufactured and supported in the United States, we provide consistent quality, fast turnaround times, and reliable technical support to help you deliver the best possible recreational vehicles and marine vessels to your valued customers.

  • What types of tanks can your systems monitor, and what extra features are available?

    Our versatile systems are designed to accurately monitor fresh water, grey water, black water, and fuel tanks all from a single, streamlined interface. Beyond basic level sensing, we offer optional features to enhance your monitoring experience, including programmable high and low alarms and integrated battery voltage displays. This comprehensive monitoring capability ensures you are always aware of your utility levels before they become an issue. Whether you are dry camping in an RV or offshore cruising on a boat, our adaptable configurations provide the critical data you need for a safe and comfortable journey.
