SENDERS
FUEL AND WATER LEVEL SENDERS No moving parts, nothing to break or wear out Prevents pointer bounce Can be cut and calibrated in the field Available in 12 or 24 volts Detect water in fuel Other ohm resistances available Requires 12 volts Standard SAE 5 bolt pattern

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, it’s innovative technology renders the
traditional float arm assembly obsolete.

The fuel probe 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 meter 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 sensor probe is constructed of a PVC tube with a stainless steel wire along the outside and an insulated wire through it’s center. The readings on your meter change as the water level rises and falls on the sensor wire.

The biggest advantage to this new line of fuel & water level senders is the absence of moving parts. The unit
is impervious to mechanical failure and it greatly reduces needle bounce on the gauge. The probe comes in
12 inch increments and can be cut into any length down to the next lower increment. The probe can be built to fit tanks from 4” to 120” deep and is available for standard as well as custom tank installations, a 3 terminal unit requires 12 volts to the sender.

Note: If ordering cut & calibration, please have the following information when ordering:
  - Depth of tank
  - Specifiy gas, diesel, or gasahol
  - for other ohms, have fuel type and brand of gauge
