Veratron Deep-Pipe Level Sender - 800mm - 90 to 4 OHM

The Veratron Deep-Pipe Level Sender – 800mm – 90 to 4 OHM is a precision fuel tank monitoring system designed for marine, automotive, and industrial applications where accurate liquid level detection is critical. Built by Veratron, a leader in marine and automotive instrumentation, this sender transforms raw tank data into reliable gauge readings on your dashboard. Whether you're upgrading a classic restoration project, installing aftermarket gauges on a custom build, or maintaining a vessel's fuel management system, this sender provides the accuracy and durability that professionals demand.

The unit employs a 38mm diameter vertical tube housing a precision float mechanism that responds directly to fuel level changes within the tank. As fuel rises and falls, the float moves up and down, varying resistance from 90 ohms (empty) to 4 ohms (full), which your gauge cluster interprets and displays in real time. Small baffle holes positioned at the top and bottom of the tube prevent fuel sloshing and inaccurate readings during acceleration, braking, or rough water conditions—a critical feature for vehicles and boats operating under demanding conditions. The 800mm depth accommodates deep fuel tanks common in trucks, RVs, and larger marine vessels, ensuring full-range sensor coverage without dead zones.

Mechanics and fabricators integrating this sender should verify tank mounting boss compatibility with the 38mm diameter tube and confirm that onboard gauges accept the 90–4 ohm resistance range—most OEM and quality aftermarket instruments support this standard. Installation requires careful handling to avoid float damage and proper sealing to prevent fuel leaks. The lightweight design (1 lbs) minimizes tank load, and the robust construction ensures years of fade-free operation in gasoline, diesel, and marine fuel environments. Whether restoring a vintage truck, building a performance fuel system, or upgrading marine instrumentation, the Veratron sender delivers the reliability and accuracy that serious builders expect.
