Peak Fuel Efficiency
Accurate fuel consumption and boat speed data allow you to determine
peak fuel efficiency. As shown in the opposite diagram, peak fuel efficiency
changes constantly according to sea conditions, boat characteristic, trim
tab setting, and weight load/distribution. FloScan allows you to pinpoint
the engine speed that will cover the most ground with the least amount of
fuel consumed under any load or operating condition. No other piece of
marine equipment allows you to master this procedure as quickly or
effectively than FloScan.
Diesel Models
Diesel models are based on the type of fuel delivery system used and
each engine requires a dedicated FloScan system. These engines use
a variety of fuel pumps including rotary, in-line, and direct injection
systems. Flow sensor selection is based on the feed and return flow rates
associated with the engine. Flow sensors are installed on the feed and
return lines to display net flow rate and total fuel consumption. Certain
engines which use the return fuel to cool injectors will require fuel
temperature compensation to ensure accurate flow measurement. These
engines include Detroit Diesel
TM
, EMD
TM
, and CAT
TM
3100/3500 Series
engines and are limited to the Series 7000 and 9000 Multifunction
Systems only. All models require a panel mounted SPST (ON/OFF)
switch for resetting the totalizer. Series 9000 diesel models require an
additional SPST switch for selecting GPH or nautical MPG.
Easier-to-Install Series K Diesel System
The new Series K Diesel System represents a major breakthrough in
diesel fuel management. The Series K system cuts the installation time
and cost in half over previous diesel models. Separately mounted
pulsation dampers are no longer required. New flow sensor design also
enhances system performance and accuracy. Simplified procedures allow
for do-it-yourself installation. Models available for diesel engines from
25 to 4300 hp.
Gasoline Models
Gas models are the easiest to specify and install. We fit the following
engine types:
-ALL carbureted Inboard, I/O, and Outboard gas engines.
-ALL 2-stroke and 4-stroke EFI Outboard gas engines.
- ALL DFI gas O/B engines including Mercury Optimax
TM
and Evinrude
Ficht
TM
.
- ALL EFI Inboard and I/O gas engines with closed loop return fuel systems
such as Mercruiser
TM
and Volvo
TM
engines.
FloScan now fits EFI Inboard and I/O engines with fuel return lines
that are connected directly to the fuel tank such as Crusader
TM
, Marine
Power
TM
, PCM
TM
, SeaMaxx
TM
and Kodiak
TM
EFI engines. Flow sensors are
installed on the feed and return fuel lines to measure the net burn rate of
the engine. See Series 5800 CruiseMaster section for more info.
When selecting a gas CruiseMaster or TwinScan model, use the following
formula to determine the correct GPH scale (HP rating x 10% = maximum
GPH). Example: 200 hp x 10% = 20 GPH. Select the CruiseMaster model
with the 0-20 GPH scale or TwinScan model with 0-24 GPH scale.
Multifunction and GPS Interface Models do not require scaling since they
incorporate a digital display which reads up to 999 GPH. Make sure to
select proper flow sensor type (20B/231/233 Series) for your application.
Flow sensors are typically installed in-line after the filter for added protection
from fuel tank debris. With certain EFI engines such as Mercruiser, the
flow sensor can only be installed before the filter. Adding a basic (coarse)
filter element before the sensor provides adequate protection.
All models require a panel mounted SPST (ON/OFF) switch for resetting
the totalizer. Series 7000 gas models require two additional SPST switches
for selecting Port or Stbd GPH and Engine Hour Time or Engine Synch.
Series 9000 gas models require a third SPST switch for selecting GPH or
nautical MPG.
Model Selection and Installation Tips
Monitors Your Engines Heartbeat
FloScan serves as a watchdog on engine performance. For example, if
your GPH increases from what you’ve already determined to be an efficient
operating level, you’ll know something’s amiss... a nicked prop, fouled
hull, clogged injector, engine problem, etc. Even something as simple
as a defective spark plug can up your fuel consumption by 20% - 40%,
with no noticeable change in engine operation.
