Default Livorsi Introduces Precise Readings with Fuel and Water Level Senders

Fuel & Water Level senders provide an accurate, continuous readout of fuel or water levels even in a moving boat. Consisting of a single in-tank probe and an amplifier, its innovative technology renders the traditional float arm assembly obsolete.

The fuel sender itself is constructed of concentric tubing (a small brass or aluminum tube inside a larger aluminum tube) that's placed vertically in the tank. Acting as a capacitor, the inner tube reads how much air is in the tube and changes in value as the fuel level rises or falls. The amplifier converts these values to a signal suitable to drive a standard gauge or other display. The capacitor can even detect water in the fuel tank. The sender is easily installed in the standard float arm assembly mounting plate, an SAE standard 5 bolt pattern.

The water sender is constructed of a PVC tube with a stainless steel wire along the outside and an insulated wire through its center. The readings on your gauge change as the water level rises and falls on the sensor wire.

The biggest advantage:

The absence of moving parts = resistance to mechanical failure
Greatly reduces needle bounce on the gauge, as reading is unaffected by side to side or forward motion.
Easily installs into the standard float arm assembly mounting plate.
Available for standard as well as custom tank installations

These senders can be built to fit tanks from 4" to 120" deep, with your choice of 12 or 24 volts. Available in 12 inch increments and can be cut into any length down to the next lower increment. A 3 terminal sender is offered for Smartcraft™ applications.

No Surprises with Redline gauges!
The Redline gauge series match your Waterproof gauges with an additional L.E.D. light to warn of specific temperature, pressure or level concerns based on built-in set points. Whether you're boating from dawn to dusk, these L.E.D. lights are visible even in direct sunlight.

Select from: fuel level, oil temp, water temp, fuel pressure or oil pressure, all have a 2 1/16" cut out. For more information please visit
