Veratron Deep-Pipe Level Sender - 210mm - 90 to 4 OHM

The Veratron Deep-Pipe Level Sender – 210mm – 90 to 4 OHM is a precision fuel tank measurement instrument designed for marine, RV, and automotive fuel system monitoring. This sender delivers accurate real-time liquid level data to your gauge cluster, making it essential for drivers who need reliable fuel consumption tracking and tank status visibility. Whether you're running a custom fuel system, upgrading an older vehicle's gauge accuracy, or installing aftermarket instrumentation, this deep-pipe design ensures consistent readings across the full range of tank capacity.

Built with a 210mm vertical tube housing, the sender contains a precision-engineered float mechanism that rises and falls with fuel level changes, modulating resistance from 90 ohms (empty) to 4 ohms (full). The baffle design—small orifices at the top and bottom of the tube—dampens fuel slosh and vibration, preventing erratic gauge needle fluctuation that plagues poorly designed senders. This dampening system is critical for highway stability; without it, cornering or acceleration causes false readings that confuse drivers about actual fuel status. The ohm-to-fuel mapping is industry-standard, ensuring direct compatibility with most aftermarket and OEM gauge clusters that expect this resistance curve.

Mechanics and fabricators rely on Veratron senders for custom fuel tank installations, fuel cell retrofits, and gauge system replacements where stock senders are unavailable or unreliable. The 210mm depth suits mid-depth to deep tanks common in trucks, hot rods, and marine applications. Installation requires basic wiring—signal wire, ground, and tank reference—and integration with any 90-4 ohm gauge sender circuit. Verify your gauge cluster's resistance specification before purchase to ensure proper needle response and full-scale accuracy across the tank range.
