IMPORTANT
Always install the Fuel Flow Transducer AFTER the primary lter. The primary lter must be
a good quality water separator type with a minimum ltration of 30 microns or better. (10 or 2
micron. The lower the micron rating the ner the ltration) Failure to provide this level of
ltration protection will result in inaccurate readings or total failure or damage to the transducer.
If there is not a suitable length of hose after the primary lter, an in-line lter (30 micron or
better) should be tted before the Fuel Flow transducer. Damage due to insufcient ltration
is not covered by warranty. If in doubt please consult your local
Marine dealer for advice
prior to installation.

Always wire your Fuel Management Gauge into your boat’s ignition so that when the
engine is turned on, the gauge is recording the fuel used. If an accessory switch is used
and you forget to turn the unit on then the gauge will not have recorded the fuel used
and will be inaccurate. If you are unsure how to do this, contact a qualied marine
electrician.
The Fuel Management Gauge is designed
for above or below deck installation.

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.
Connect the red wire from the gauge to
the positive supply through a 1 amp fuse
or a 1 amp circuit breaker . Connect the
green wire from the gauge to the
electrical ground.
Connect the fuel transducer to the
gauge as follows:

Installation of the fuel transducer
The fuel transducer is designed for
installation in Coast Guard approved 3/8"
fuel line. The transducer MUS T be
installed AFTER the main fuel .
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.
Drain all the fuel from the fuel line. Cut
the fuel line and using the fuel hose attaching
clips provided install the transducer so that the
FUEL IN side of the transducer connects to the
fuel tank.

Instrument Setup
Select units of measure
display fuel values in US gallons, Liters or
Imperial gallons. To change the current
display setting, perform the following steps.
1. Power up the unit while holding key.
Press and hold during power up
2. Once the unit is on, release the key.
The current display setting is indicated as
pictured below:
3. To select another display setting, use the
up or down keys to change the value.
or
4. To save the change and exit this mode,
press and hold both keys simultaneously
for one second.
Press and hold for one second
The fuel values are now displayed using the
new setting.
Calibration
The fuel transducer supplied with the fuel
ow meter will provide readings at better
than 5% accuracy. Individual calibration
will increase this level of accuracy to better
than 2% over
gallons per hour.
1. Reset the total log value to zero(see pg 9)
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
the instrument may require calibration.
4. Apply power while holding
key.

Flow Averaging
The Flow Averaging function sets the
averaged. The time period can be set in
the range of 1 to 99 seconds. Normally,
engines do not draw fuel from the tank
ata constant rate. An engine draws fuel
ata high rate for a short time until the
carburetor bowl or injection reservoir is
full and then draws no fuel for a few
displayed, it would be too erratic to read.
Usually, a value of 10 -15 seconds gives
satisfactory results for two stroke
naturally carburetored engines. Four
stroke and engines that use electronic
fuel injection may require longer
periods. If the readings seem erratic,
you can increase the time period.
A long time period means the fuel
display will have a slow response time
and a more accurate reading. A short
time period means the display will have
a quick response time but an erratic
remaining measurement in terms of
accuracy.
Flow Average Menu
Follow the steps outlined below to enter
the Flow Averaging Menu:
1.Press and hold the
key while
applying power to enter the Fuel
Calibration menu.
2. Press and hold both keys
simultaneously for 2 seconds to enter
the Flow Filter mode.
3. The Fuel Flow Average Period menu
AVG is displayed with the default
value of 10 seconds if you have not
previously changed it.
4. Use the up or down keys to change
the value between 1 and 99 seconds.

Troubleshooting Chart
No display
1 Check the DC power connections and DC polarity with the voltmeter.
2 Check fuse
No flow reading indicated
1 Check connection to the flow transducer.
2 Remove the transducer from the fuel line, and perform a no pressure flush with
the residual fuel left in transducer by covering the sensor inlet and outlet and
shaking for 20 to 30 seconds. Upon completion of the flush, finish with a low to
medium pressure (50 PSI Max) blow into the transducer from both directions
manually. When blowing through the transducer a whistling noise will indicate that
the turbine is rotating.
Low flow reading indicated
1 Check your primary and secondary filters for obstructions. If no filters are fitted this
will lead to blockage and damage of to the flow transducer (See Page 5).
1 Check your primary and secondary filters for obstructions. If no filters are fitted this
will lead to blockage and damage of to the flow transducer (See Page 5).
2 Check that the calibration is correct.
No fuel reading
High or erratic reading
1 Check that the fuel connections are well made. Air in the fuel lines will cause erratic
or high readings.
