Fuel monitor question for listers: where and how are folks mounting fuel
flow transducers on fuel injected engines? A discussion on the Lycoming
list a while back suggests mounting the Flowscan 201 in the line from the
servo to the distribution spider and supporting the line, not the
transducer, with an Adel clamp on the nearby hose to the engine sump. Is
this what most have done? anyone have some pictures to share of what they
did in this regard? Thanks for your comments.

I'm aware of three Rockets, including mine that have the transducer inline
between the Mech fuel pump and the fuel servo, along the sump. One placed his
upside down and lengthened the sump bolt and positively fastened it (he
complains of inaccuracy), the others have the hoses Adele clamped to the sump
bolts on either side and we've made sure to pull the transducer away from the
sump so that it does not touch. One is accurate, as for mine, I hope to know
in a couple of months....

I first mounted my flo transducer between the electric pump and engine driven
pump as per instructions. It was very erratic. I talked to Don at Air-Flo
and he said it should be mounted between the servo and flo divider. I made a
special fitting and mounted the transducer to the flo divider with a bracket
supporting it. It now works great. Jim Winings #34 317-718-3415

Hi Jim,
Could you clarify that you had 5" of straight tube prior and 2" of straight
tube after the flow sensor, as per instructions?
Right now I have mine set up downstream of the boost pump and filter
(located under left floor panel cover) and it is mounted to a bracket in the
center tunnel area just aft of the Firewall.
If this location is a known problem area, I will redoooo mine.

The tunnel location didn't work for me (different flow numbers with boost
pump on/off), so Ole 84 has the unit under the left front cyl, tied to the intake
tube. Works fine, last long time. Another good option would be between the
fuel controller and the flow divider -- smooth flow there.
Carry on!

Hey Mark,
Thanks for the tip. I want to be sure I understand your technique. By
"tied to the intake tube" do you mean zip tied, and where on the intake
tube, on the tube itself or on the case protrusion that extends out to meet
the tube? My fuel flow unit instruction says to mount securely with two
1/4" bolts. Tying just seems so far from that intent.
Thanks,
Jim

It wouldn't be my first spanking. Besides I might enjoy it. Maybe I could
learn how to spank others. I haven't done BFM in several years, so the
challenge stands - we'll meet in the future over Indiana.

Marty,
I have mine mounted between the Servo and the Flow Divider. It is
pretty accurate and very consistent.
I mounted a small (1.5X3") plate to two pushrod tubes with Adel clamps
and mounted the transducer to that. I have the fuel line come up
through the right front intake floor then aft to the transducer and
then to the divider. It is a straight shot through the transducer. I
also wrapped the transducer with asbestos woven material to keep the
heat down. I have photos at home, but won't be there until 3/30.
Email me around then and I can forward those to you.
One question I have concerns the line from the transducer to the
divider. I have mine as a solid aluminum line, about 4 or 5 inches
long. I have nagging concerns about the failure of this piece and
what the outcome would be so I am thinking of making it a steel line.
There isn't any relative movement between the transducer and the
divider, but I would still be more comfortable with a steel piece
there. Lots of heat cycles there.
Any Rocketeers have any thoughts on that?
