hi youtubers

jeff cote here with another session of

ask pys

so we've got a fellow voter uh stephen

and steven

uh is planning on doing a trip to alaska

and he wants to know what his gallon per

hour consumption is

on his engine um

so um he's got a four winds vista 258

um and so the first thing for fuel

monitoring is to

there's two things one is if you've got

gasoline it's easy

if you have diesel it's hard so just

remember that

diesel fuel monitoring is not easy and

the reason is

the return so not only do you draw fuel

on a diesel but you actually send fuel

back

and not only do you send fuel back but

you're sending at a different

temperature

different temperature means different

volume so the sensors have to actually

be pretty smart to know what the

temperature of the fuel coming

being pulled from the tank is and what

the temperature of the fuel coming

back in the engine is or back into the

tank

so fuel monitoring on a diesel we've

done it not trivial

um and definitely tons of sensors that

do this

but ain't easy and this is not a you

know

afternoon project if you've got a

gasoline boat

the way to monitor fuel would be to buy

something like for example garmin sells

this i think it's called the garmin fuel

sensor i think it's gfs10

they might have a newer version but

we've deployed that a lot

that sensor doesn't have a return

because it's just

gasoline so they'll actually just see

whatever the engine pulls is what the

engine uses

and it makes the calculation all easier

when you're doing when you're talking

about

measuring fuel flow for an engine you're

going to be doing that not over

nmea-0183

but you're going to be doing over enemy

a2000 these sensors

actually need an enemy a2000 backbone i

have a presentation just on that

videos just on that of course and so if

you're going to be thinking about doing

fuel flow for gasoline engine you're

going to want to have a

garment not a garment but an enemy 2000

backbone between

your chart plotter or your instruments

that are going to be able to display

the fuel burn and then also where you're

going to be mounting the fuel sensors

down in the engine room

which are going to be enemy a2000 so

diesel not easy

gasoline pretty straightforward

relatively but you will need an enemy

2000

backbone and you also want to make sure

that your charplotter whatever

generation it is

has the capability of displaying

fuel burn because you might have an nba

2000 port but depending on the software

version

it might not have the capability of

actually showing fuel burn and in that

case

you would buy a dedicated little

instrument like for example

we just did that for another boater we

installed some garmin gmi 20s

they're little instruments about this

big and those instruments allow us to

display a lot of

enemy a2000 information meritron does

the same thing there is

a huge selection of displays that you

can show for fuel burn

um from multiple different manufacturers

but remember gasoline easy diesel

extremely hard

and you'll need an me 2000 backbone and

an me 2000 compatible

display or chart plotter that will allow

you to see

fuel burn so that was a great question
