1-2 How the flow sensors work
Petrol flow sensor (FUEL 3100): The petrol
flow sensor is fitted in the fuel line between the
fuel tank and the engine. A small turbine inside
the fuel flow sensor measures the rate of the
fuel flow into the engine. This information is
relayed through the fuel flow sensor cable and
shown electronically on the display unit.
Diesel flow sensor (DIESEL 3200): A diesel
sensor is a positive displacement flowmeter,
with one moving internal part, made of low
1-3 Cleaning and maintenance
Clean the display unit and any plastic sensor
with a damp cloth or mild detergent. Avoid
abrasive cleaners, petrol or other solvents.
1-4 Calibration
FUEL 3100: It is essential to calibrate the fuel
flow sensors after installation and again after
the first 100 engine hours to allow moving
parts to wear in (see section 3-4).
2 Operation
2-1 Turning on and off
The display unit does not have its own power
switch, but if possible should be wired so that it
turns on when the engine ignition is turned on
to allow the engine hours counter to function
properly. (See section 4 -5).
2-2 The Keys
The unit has four keys, ESC, ENT,
In this manual:
•
Press means push the key for less than one
second.
•
Hold means hold the key down until the
display changes.

FUEL 3100 / DIESEL 3200 Installation and Operation Manual
friction, fuel proof plastic. There are no fine
pointed shafts and jewelled bearings to get
worn or hammered by diesel pulsing.
Each engine is fitted with two fuel flow
sensors, to measure fuel supply and return.The
system calculates the engine consumption,
compensating for pulsing from diaphragm
lift pumps, different fuel temperatures in
the supply and return lines and the flow
characteristics of the sensors.
Put the protective cover over the display when
it is not being used.
DIESEL 3200: The sensors are factory
calibrated and are highly accurate. They can be
calibrated but this should not be necessary.
Turn the unit on and off with the boat's ignition
switch. The display unit does not have its own
power switch. When the unit it is turned off,
any settings you have made are retained.
If SIM flashes at the bottom left corner of the
display, the unit is in simulation mode (see
section 2-9).
