FU60 Digital Fuel and Tank Level Gauge

The FU60 digital fuel "smart" gauge provides a highly accurate display of fuel remaining, total fuel used, fuel consumption rate and "Time-To-Go" at current rate.

The FU60 "learns" your tank and fuel sender characteristics and is accurate with ANY tank shape. Handles both 12 and 24 Volts. 5 levels of backlighting, displays gallons/liters/percent, fuel used and fuel consumption rate (gal or liters/hr). Built-in settable high & low fuel alarms. NMEA 0183 output. Can also be used to detect fuel theft.

It is compatible with all popular resistive fuel senders, both American and European. Low and High Fuel alarms can be set and the built-in 85 dB alarm will sound and the display will flash.



  • Fuel can be displayed with a resolution of 0.1 liters or gallons or as a percentage (0 to 100%)
  • Outputs NMEA 0183 serial data or may be programmed to activate an external alarm or fuel transfer pump if using a day tank
  • Contains a full data editor that can be used to enter or edit the fuel data & sender resistance values.
  • Built-in 85 dB audible alarm. Settable Low and High fuel alarms
  • Programmable lower fuel level limit to turn ON a fuel transfer pump.
  • Programmable upper fuel level limit to turn OFF the fuel transfer
  • Accuracy of better than 2% over the entire range of the fuel tank
  • Monitor is supplied in a waterproof case.
  • See Installation Instructions for more information

FU60 Digital Fuel Gauge





You "train" the FU60 to learn your fuel sender characteristics and tank shape by calibrating the FU60. You do this once (at time of installation) by filling your tank and stopping up to 20 times to tell the FU60 what the sender output means in gallons or liters at each point. The calibration data is saved into a non-volatile memory which retains the information even if the power is turned off. A built-in data editor enables you to manually enter the fuel level/sender resistance data or to make changes to exiting fuel sender calibration information.
Low and High fuel alarms can be set over the entire range of the instrument/sender. When activated, the FU60 built-in 85 dB alarm will sound and the display will flash. The alarm can be enabled or disabled with a single key press. Five levels of backlighting can be selected and all set-up, calibrations constants, alarm values, and sender calibration values are saved to non-volatile memory.

Optional ER-1 External Relay Switch


CruzPro ER-1 External Relay switch enables you to switch ON/OFF loads of up to ten amps using the external alarm outputs of your CruzPro digital gauges

  • The ER-1 External Relay switch can be connected to the "external alarm" output of the CruzPro gauge and used to switch high current loads with the normally open and normally closed relay contacts.
  • The input resistance of the control line is 10,000 ohms minimum and a Control voltage of between +3.5 to +12 VDC can be used to switch the relay from OFF to ON.
  • The external relay switch is powered by 12 or 24VDC and typically draws only 0.035 amps when the relay is switched ON and almost no power when the relay is switched OFF.
  • Relay Contacts 10 Amps maximum.
  • Both NO (Normally Open) and NC (Normally Closed) contacts
