What about the fuel flow sensor?

[msbelton]

Hi Jim,

Thanks for the information. Very good. You usually post your
remarkable fuel usage with great detail, so I'm a little curious do
you use a fuel flow sensor for these numbers fed into your EIS?

I'm consider replacing the majority of the analog gauges, ie. EGT
and CHT analog gauges with the EIS, and it seems you take advantage
of the whole package. I appreciate the information.

Thank you,

Mark

My panel is set up how I like it - It fits my scan and overall stays
pretty simple with the main info I need.

I don't have the fuel flow option on my EIS - That option was more
money than what I wanted to pay. My fuel numbers are based on total
useage versus total time the engine was run, including ground time,
t/o, climb, cruise, decent, and messing around. The difference
bewteen 1.8 gph and 2.6 gph is dependent on what rpm I run at. The
fuel flow would help to monitor that in flight, but I figure gas
timewise and use a mirror system to actually look at whats in the
fuel tank - I generally don't fly at just one speed very long anyway -
I like to play too much. I plan at 2.6 gph, but usually average
about 2.1 at 5200 to 5300 rpm. If I am running in the 65-75 mph
speed range (usually in the 4200-4800 rpm range) I am usualy at 1.8-
2.0 gph range, when at 80-90 (usually in the 5100-5300 range) about
2.1-2.2 gph useage and when up about 95 or so (usually in the 5500-
5600 range) I am usually around 2.5 as a norm. Hope this makes some
sense.

Jim, can you translate that to mpg at those different throttle settings?

I haven't really done that to a specific rpm - I have tracked the mpg
on each trip I have taken and I have been as low as 31 and as high as
39 mpg but most of the time I normally average a little more than 34.
