Calibration
The fuel transducer supplied with the fuel flow meter
will provide readings at better than 5% accuracy.
Individual calibration will increase this level of
accuracy to better than 2% over a fuel flow range of
10.0 to 120 litres per hour. Use the following steps to
calibrate your fuel flow meter:
1. Reset the total log value to zero (see previous
page).
2. Use a known amount of fuel. The larger the
amount the more accurate the calibration will
be.
3. Take note of the actual volume of fuel used and
the fuel used indicated by the total log. If these
two totals are different the instrument may
require calibration.

WARNING
IT IS VERY IMPORT ANT TO INST ALL A FUEL FIL TER BETWEEN THE FUEL FLOW TRANSDUCER
AND THE FUEL TANK. THIS FILTER WILL CATCH LARGER PARTICLES OF DIRT FROM THE
FUEL T ANK AND PREVENT THE FINE GAUZE FIL TER IN THE FUEL FLOW TRANSDUCER FROM
BECOMING BLOCKED AS THIS MA Y DAMAGE THE ENGINE.
Location
The FUEL 2100 is designed for above or below deck
installation. Select a position that is:
• On a flat surface
• At least 300mm (12") from a compass
• At least 500mm (20") from any radio
• Easy to read by the helmsman and crew
• Protected from physical damage
• Accessible to electrical cable connections
Instrument
Panel
51mm (2”)
Mounting
The instrument panel must be 3mm to 19mm
(1/8" to 3/4") in thickness.
• Drill a 51mm (2") hole in the instrument panel.
• Remove brackets and insert the instrument so
the back is flush with the instrument panel.
• Slide the bracket over the instrument and
tighten the mounting nut until secure.

Wiring Connection
• Keep electrical and transducer cables away
from alternator or other noise generating
electrical cables. Avoid connecting the
instrument to power circuits that share loads
with ignition, alternators, inverters and radio
transmitters. Electrical power supply
connections should always be as short as
possible.
BRACKET
FUJI 5-PIN
CONNECTOR
• Connect the red wire to the positive supply via
a 1 amp fuse or a 1 amp circuit breaker.
Connect the black wire to the electrical ground.
• Connect the fuel flow transducer to the five pin
transducer inlet cable.

Installation of the fuel flow
transducer
The fuel flow transducer is designed for installation
in Coast Guard approved 9.5 mm
(3/8”) flexible fuel line. The transducer MUST be
installed AFTER the main fuel filter. It should be
located well away from any area where it will be
effected by excessive heat or vibration from the
engine. It is preferable to mount the transducer in a
vertical position.
8
RED
(+) TERMINAL
Drain all the fuel from the flexible fuel line. Cut the
fuel line and using the fuel hose fixing clips provided
install the transducer so that the FUEL IN side of the
transducer connects to the fuel tank.
Audio and visual alarm indicates remaining fuel
total has dropped below a preset alarm value.
• Flow
2.5 to 160 litres per hour
0.5 to 43 US gallons per hour
0.4 to 36 imperial gallons per hour
• Logs
Logs record fuel used up to 999 display units.
T ot al Log is saved in memory at power down.
Both Trip Log and Total Log can be reset via the
keypad.
Display is backlit for
Night Operation
• Fuel Remaining
User enters a fuel value into memory via the key
pad. The quantity of fuel used is automatically
subtracted from this total. This value remains in
memory at power down.
• Operating Voltage
8 V DC to 16.5 V DC.
• Operating Temperature
0 to 50°C (32 to 122°F).
• Current Drain
70 mA max.
• RF Interference
<6 dB quieting on any marine radio channel
(with 3 dB gain antenna) within one metre of the
instrument. Complies with CE EMC standards
EN50081-1 and EN50082-1.

Appendix B - Troubleshooting Chart
No display:
1. Check DC power connections and DC polarity with voltmeter.
2. Check fuse.
No flow reading indicated:
1. Check connection to flow transducer.
2. Remove transducer from fuel line, blow through transducer, a whistling noise will indicate the
turbine is rotating.
Low flow reading indicated:
1. Check that the gauze filter is clean. If the filter is not installed fine strands may clog up the
turbine.
2. Check calibration is correct.
High or erratic reading:
Check fuel connections are well made. Air in fuel lines will cause erratic or high readings.
