<<I want to add a fuel metering system.
I never know exactly how much fuel I have burned on a particular run.
I would like to add a metering system whereby I can tell how much fuel I have
burned in each engine.
A simple fuel-flow meter won't do, since not all the fuel is burned.
I would like the meters to be mechanical, plumbed to the fuel system in the
engine room with no electronics/electrics involved, sort of like the meters on
the pumps when you fuel up.>>
Well, you could install Flowscan meters on each engine but that would cost
quite a few bucks more than wooden dip sticks. If a fuel consumption reading
with a probable error within 10% would do, you might consider putting engine hour
meters on each engine. This takes advantage of the fact that most trawler
owners spend approximately 80% of the engine on time at "cruising" speed.
Generators too operate within a narrow speed range. A simple chart relating fuel
consumption to hours of engine useage would give you a reasonably accurate measure.
On my Willard, there is no factory installed fuel measurement system. Even
the manual suggests using a dip stick. Still, by keeping track of engine hours,
we can estimate the fuel useage within a 10% range without trouble.
