Veratron Deep-Pipe Level Sender - 290mm - 0 to 180 OHM

The Veratron Deep-Pipe Level Sender – 290mm – 0 to 180 OHM is a precision fuel tank level measurement instrument engineered for boats, RVs, and specialty vehicles requiring reliable liquid monitoring in deep or irregularly shaped tanks. This sender bridges the gap between basic float switches and complex electronic fuel management systems, offering mechanics and boat builders a proven solution for accurate gauge readouts without the complexity of capacitive or ultrasonic alternatives.

At its core, the Veratron sender uses a buoyant float mechanism housed within a 38mm diameter vertical tube—the 290mm length accommodates deeper tanks where standard 240mm units fall short. As fuel level changes, the internal float rises and falls, modulating resistance across the 0–180 OHM range in direct proportion to tank capacity. The tube features small baffle holes at the top and bottom that dampen fuel slosh and prevent erratic needle swings on the instrument cluster, ensuring stable, readable feedback even during acceleration, braking, or rough water conditions. This dampening design is critical for applications where vibration and tank sloshing would otherwise cause gauge flutter.

Mechanics and boat builders favor this Veratron sender for marine auxiliary fuel tanks, auxiliary freshwater or waste tanks in RVs, and custom automotive builds where OEM gauge clusters accept analog resistive inputs. The 0–180 OHM output is compatible with most Veratron and Teleflex fuel gauge clusters, making installation straightforward for those familiar with resistive sender wiring. Weight of just 1 lb and the compact 38mm tube diameter simplify mounting in tight or unconventional tank configurations. Before installation, verify your gauge cluster's OHM range—this unit is specifically calibrated for 0–180 OHM instruments and will produce inaccurate readings if wired to gauges designed for different resistance curves.
