Flow transducer, overhead panel | 1.17.2021

Figured that since I've been working on sensors lately, now would be a good time to get the fuel flow transducer mounted. In retrospect, I did this and then realized that the hose routing probably won't work because of the cooling plenum, and I'm not sure how I'm going to route it now. It might still work where it is. Maybe bummer?

This is the transducer. It measures fuel flow, so that you can calculate fuel burn, monitor usage, etc.

I don't have any good pictures, but I fabricated hoses and then wrapped the transducer itself in fireshield. It was then attached to the fuel servo, and the fuel servo was re-installed for good (hopefully).

As a side note, there is so much conflicting mounting advice on this little sensor, even from the manufacturer themselves. I spent a ton of time trying to find the best place to mount it and decided on an "outlet up" orientation, on the line that supplies the fuel spider.

I then moved on to figuring how to mount the overhead switch panel. The manual doesn't give much (if any?) instructions on how to do this, so I decided on attaching it with nutplates to the carbon door posts. I also forgot how itchy carbon fiber is (even if only drilling a little bit), and subsequently regretted not wearing a long sleeve.

Nutplate held in with a screw for drilling the rivet holes, since I don't have a jig.

Pretty standard install here, and I think this will end up being the best solution.

The edges will get sanded to fair them in better, but this seems like it will work great.

While I worked in the garage, Emily worked upstairs on a mockup for the seat bottom upholstery in a cheap remnant vinyl that we had, which came out pretty awesome.

That's it for today!
