Navico Fluid Level Sensor
Navico Fluid Level Sensor — Product description
Upgrade your boating experience with seamless tank monitoring that keeps you informed without the guesswork. The Lowrance Fluid Level Sensor bridges the gap between traditional analog tank senders and modern digital displays, delivering precise fluid levels across your NMEA 2000 network. Whether you're tracking fuel on long offshore runs or checking freshwater reserves during family outings, this sensor ensures you're always one step ahead.
Key Features That Stand Out
- Versatile Fluid Monitoring: Starts pre-configured for fuel tanks but easily adapts to water, gray water, live wells, oil, or black water—perfect for diverse vessel setups.
- Precision Calibration: Factory-tuned for U.S. marine standards (33.5 to 240 inches), with options for 2-, 3-, or 5-point recalibration to match European senders or custom tanks using compatible multifunction displays.
- Plug-and-Play Simplicity: Includes a 10-foot cable and Micro-C T-Connector for quick integration into existing NMEA 2000 backbones—no complex rewiring needed.
- Reliable Data Transmission: Outputs levels from 0-100% in real-time, replacing older models like the EP-65 while enhancing network compatibility.
How It Integrates Seamlessly into Your System
Picture this: Your boat's analog tank sender—likely a float-based unit common in marine applications—sends a variable resistance signal. The Fluid Level Sensor converts that into standardized NMEA 2000 PGN messages (like 127505 for fluid levels), broadcasting data to Lowrance, Simrad, or B&G chartplotters, gauges, or apps. This means a single network glance shows exact percentages, instances (e.g., Fuel Instance 0), and even temperature if supported.
Configuration happens through your MFD's menu: Select the sensor, assign tank type and instance, then calibrate by filling/draining to key points. It's intuitive for seasoned skippers and approachable for weekend warriors, minimizing downtime and maximizing safety.
Step-by-Step Installation Tips for Smooth Setup
- Power down your NMEA 2000 network and locate the tank sender wires (typically ground, power, and signal).
- Connect the sensor's terminals directly to the sender: Match polarity carefully to avoid shorts.
- Snap the T-Connector into your backbone, route the 10-foot cable securely away from heat or vibration sources.
- Power up, add the device to your network via the MFD, and calibrate—start with empty, then 25%, 50%, etc., for accuracy.
- Test by observing level changes on your display; tweak instance numbers if multiple tanks are in play.
Pro tip: Use drop cable strain relief and weatherproof connectors in exposed bilge areas to ensure longevity against saltwater corrosion.
Why Boaters Trust This for Peak Performance
Beyond specs, it's about peace of mind. No more eyeballing sight tubes or relying on faulty gauges—get data-driven decisions that prevent running dry mid-trip or overfilling holds. It's rugged for harsh marine environments, with robust housing that withstands spray, humidity, and shocks. Anglers love it for livewell management; cruisers appreciate multi-tank oversight. Compared to standalone monitors, NMEA 2000 integration centralizes info, reducing clutter and wiring hassles.

Frequently Asked Questions
What types of tanks can the Lowrance Fluid Level Sensor monitor?
It's pre-set for fuel but configurable for water, gray water, live wells, oil, and black water tanks via compatible displays.
Does it work with non-U.S. tank senders?
Yes, it supports calibration for European standards and custom resistances using 2-, 3-, or 5-point methods on MFDs.
How do I calibrate the sensor for accuracy?
Access the configuration menu on your Lowrance, Simrad, or B&G display, select calibration points (e.g., empty, quarter, half), and adjust based on actual tank levels.
Is installation DIY-friendly for average boat owners?
Absolutely—simple wiring to the sender, T-Connector to the backbone, and menu-based setup. Basic tools like wire strippers suffice.
Can it handle multiple tanks on the same network?
Yes, assign unique instances (e.g., Fuel 0, Water 1) during configuration to distinguish data on your displays.
What's the cable length, and can it be extended?
Comes with 10 feet; extend via standard NMEA 2000 drop cables if needed, keeping total backbone drops under network limits.
Does it replace the EP-65 fluid level sensor?
Yes, it serves as a direct upgrade with improved configurability and broader compatibility.
Transmits the tank level from a suitable tank level sender unit on the the NMEA 2000 network.
