Veratron Deep-Pipe Level Sender - 1000mm - 240 to 33 OHM

The Veratron Deep-Pipe Level Sender – 1000mm – 240 to 33 OHM is a precision fuel tank monitoring instrument engineered for marine, RV, and automotive applications where accurate liquid level measurement is non-negotiable. This sender transforms a simple float mechanism into reliable electrical feedback, allowing your gauge cluster to display real-time fuel quantity without guesswork. Whether you're diagnosing a faulty fuel gauge, upgrading a classic restoration, or installing auxiliary tank monitoring on a custom build, this deep-pipe design addresses the specific challenge of measuring fuel in tanks requiring extended probe depth.

At 1000mm in length, this sender is built for deep fuel reservoirs where shallow probes cannot reach the bottom, ensuring complete level range visibility from empty to full. The float-based mechanism operates on a variable resistance principle, outputting between 240 ohms (empty) and 33 ohms (full)—a swing that integrates seamlessly with most OEM and aftermarket gauge clusters. The 38mm diameter tube design includes baffle holes at top and bottom that regulate fuel flow around the float, eliminating sloshing errors and providing stable, accurate readings under acceleration, braking, and cornering. Stainless steel and brass construction resists corrosion in fuel environments, critical for long-term reliability in tanks exposed to ethanol blends or marine conditions.

Mechanics and fabricators commonly specify Veratron senders for fuel system upgrades, tank replacement projects, and gauge troubleshooting where OEM parts are unavailable or cost-prohibitive. Compatibility spans most 12V and 24V automotive and marine electrical systems that accept standard 240–33 ohm senders; verify your gauge's input range before installation to ensure proper calibration. The 1000mm length suits auxiliary tank builds, deepwell fuel cells, and original equipment applications in larger vessels where standard short-arm senders fail to reach the tank bottom. Installation requires basic electrical knowledge—sender ground, signal wire to gauge, and tank port threading—making it accessible to both professional shops and experienced DIY builders performing fuel system diagnostics or modifications.
