<h3>Maretron: Intelligent Vessel Monitoring &amp; Control</h3><p><strong>Maretron</strong> has long been recognized as a leading innovator in marine electronic instrumentation, <a href="/11272-maretron">designing and manufacturing advanced monitoring and control systems</a> for recreational and commercial mariners alike. Now part of the Raymarine family, Maretron's product ecosystem continues to set the standard for vessel intelligence, safety, and operational efficiency on the water.</p><p>At the heart of the Maretron platform is the open <strong>NMEA 2000&reg;</strong> standard — an industry-wide protocol that allows electronic equipment from multiple manufacturers to communicate seamlessly over a single network backbone. Maretron was among the first companies to offer NMEA 2000&reg;-approved cables and connectors, and that commitment to interoperability remains central to everything they build.</p><h3>A Complete Ecosystem for the Modern Vessel</h3><p>Maretron's product range spans nearly every monitoring need a mariner might have. Their <strong>vessel monitoring and control</strong> hardware includes touchscreens, black box display servers, and alarm modules that put critical data at your fingertips — whether you're at the helm, below deck, or monitoring your boat remotely via the MConnect&reg; web server. MConnect integrates with over 400 NMEA 2000 data points, delivering real-time feedback through customizable graphics on chartplotter displays or any browser-enabled device.</p><p>Engine health is a top priority for any serious boater. Maretron's <strong>engine monitoring modules</strong> track vital parameters like oil pressure, coolant temperature, RPM, and fuel flow, providing programmable alerts before minor issues become costly problems. Their <strong>electrical monitoring</strong> lineup covers both AC and DC systems, helping owners keep tabs on battery voltage, current draw, and shore power status across the entire vessel.</p><p>For boat owners who need to track fluid levels, Maretron's <strong>tank monitoring</strong> solutions connect to resistive tank senders from leading manufacturers, converting analog readings into NMEA 2000 digital data. Navigation-focused products include the WSO200 Ultrasonic Wind and Weather Station, the DST110 Depth/Speed/Temperature Triducer, the GPS200 GPS Antenna/Receiver, and the SSC300 Solid State Compass — each engineered to deliver dependable data in demanding marine environments.</p><h3>Built to Withstand the Marine Environment</h3><p>Every Maretron product is tested and certified to the <strong>IEC 60945 standard</strong> for Maritime Navigational and Radiocommunication Equipment and Systems. Electronics — even those installed below deck — are housed in watertight enclosures engineered for years of reliable service in saltwater, humidity, and vibration. Gold-plated terminals, nickel-plated brass connectors, and triple-shielded cabling reduce EMI and prevent the corrosion that ends the life of lesser marine electronics.</p><p>The <strong>MPower&reg; Digital Switching</strong> platform extends Maretron's capabilities into DC electrical system control, allowing boaters to manage circuits via configurable keypads, switch modules, and chartplotter integration. The <strong>OctoPlex</strong> power distribution system takes this further, offering complete AC and DC control with significant savings in wiring weight and installation complexity.</p><h3>Why Mariners Choose Maretron</h3><ul style="list-style:disc"><li>Pioneer of NMEA 2000&reg;-approved cables and connectors</li><li>Full ecosystem: sensors, displays, gateways, switches, and software</li><li>IEC 60945-certified for harsh maritime environments</li><li>MConnect&reg; enables remote vessel monitoring from any browser-enabled device</li><li>Compatible with engines from Caterpillar, Cummins, Yanmar, Volvo Penta, and more</li><li>Now backed by Raymarine's global support network</li></ul><p>Whether you're outfitting a coastal sailboat, a long-range trawler, or a commercial workboat, Maretron delivers the tools to keep you informed, in control, and safe on the water.

Product Details

The Maretron TFT-5H is a non-displacement hull focus tube designed as an essential accessory for TLM100 and TLM150 ultrasonic tank level monitors. This focus tube enables accurate tank level measurement on vessels with planing hulls or sailboats that experience extended periods of pitch or roll beyond 6 degrees.

Key Features:

  • SAE J1810 5-bolt mounting pattern for direct installation to standard tank openings
  • Extends operational pitch and roll tolerance from 6° to 15° for improved accuracy on non-displacement hulls
  • Directs ultrasonic waves straight down to fluid surface and back, compensating for hull angle
  • Field-trimmable design allows customization to tank depth (trim to reach 1" above tank bottom)
  • Includes gasket and focus tube cap for proper sealing and signal reflection
  • Compatible with diesel, fresh water, waste water, black water, and oil tank applications
  • Constructed from durable materials suitable for marine environments

The TFT-5H mounts between the tank opening and the TLM100/TLM150 sensor component, creating a tube that guides ultrasonic signals directly to the liquid surface regardless of vessel attitude. The included focus tube cap ensures proper signal reflection even when tank bottoms are uneven, and helps keep solids away from the transducer in black water applications. Installation requires trimming the tube to the appropriate length using a metal-cutting blade, then securing with mounting hardware (torque to 10-15 in-lbs). This accessory is essential for powerboats with planing hulls that spend significant time with the bow pitched up during operation.
