AxonRF nowire Wireless Tank Monitoring System: Wireless, Retrofit-Friendly Level Sensing
AxonRF, Inc. introduced the nowire Wireless Tank Monitoring System to eliminate the clutter and difficulty of running wires between tank sensors and the display panel. Designed as a retrofit-friendly solution, the nowire system aims to simplify tank level monitoring by replacing traditional wired installations with a wireless sensor network that conforms to industry wireless standards.
Key Features and Standards
The nowire system complies with the IEEE 802.15.4 wireless standard, a reliable, low-power radio protocol often used for short-range wireless sensor networks. AxonRF emphasizes that the product is easy to install and highly reliable, and it does not require special tools or advanced technical knowledge for installation. That makes it an attractive choice for owners and technicians who need a straightforward monitoring upgrade without complex rewiring.
Sensor Technology and Tank Compatibility
One of the notable advantages of the nowire sensors is their ability to read fluid levels through common plastic tanks used for fresh, gray, and black water. Because the sensors can detect levels through tank walls, there is no need to cut holes for sensor probes or to modify tank integrity. This non-intrusive sensing approach reduces the risk of leaks and preserves the original tank structure.
Maintenance Advantages
AxonRF reports that the nowire sensors require no calibration, cleaning, or regular servicing. By removing the need for physical penetration of tanks, the system minimizes potential maintenance points and simplifies long-term ownership. For users who prefer a set-and-forget monitoring solution, these characteristics make the system particularly appealing.
Power Options and Expandability
The nowire Wireless Tank Monitoring System offers flexible power options to suit different installations. It can be powered by 12/24V DC house power commonly found on vehicles and vessels, or it can run on two AA batteries for installations where wired power is not available or desirable. The system is scalable as well: a single setup can be expanded to monitor up to three tanks and support up to four display units, allowing owners to centralize tank information in multiple locations.
Cost and Availability
Retail pricing for a single-tank kit starts at $199.50, making the nowire system a competitively priced option for anyone looking to upgrade from a wired tank monitoring setup. The product is produced by AxonRF, based in Kirkland, Washington. For direct inquiries, the company can be reached by phone at (425) 298-8046.

Who Benefits from a Wireless Tank Monitoring System?
Owners and technicians who manage plastic storage tanks for potable and waste water benefit from a wireless monitoring solution in several ways. The absence of physical wiring reduces installation time and expense, enables simpler retrofits in existing systems, and avoids the structural compromises associated with through-tank sensors. Because the nowire sensors read through tank walls and eliminate the need for drilling or seal fittings, the approach helps maintain tank integrity and reduce long-term maintenance concerns.
Practical Considerations
When evaluating wireless tank monitoring solutions, consider placement of displays and sensors, radio environment, and power preferences. The nowire system’s compliance with IEEE 802.15.4 supports reliable short-range communication, but like all wireless systems, performance can depend on factors such as antenna placement and environmental obstructions. The system’s battery option provides flexibility for locations without convenient DC power, but users should plan for periodic battery replacement according to their usage pattern.
AxonRF’s nowire Wireless Tank Monitoring System offers a practical, non-intrusive alternative to traditional tank probes and wired monitors. Its retrofit capability, no-drill sensing, multiple power choices, and expandable architecture make it a convenient option for those looking to modernize tank level monitoring without complicated installation.
