Thanks Steve Rather than reroute the fuel lines I think I’ll build a little processor and measure pulse widths and rpm and create a pulse stream fr the dynon to read. Any hints on anything to watch out for in coding? Cheers Steve > On 27 Jul 2017, at 12:39 pm, Steven W.

I can get one that has two flow meters but that makes installation complicated and not really cost effective. I am looking for something that works off the injectors. As usual it has to be "tweaked" with actual fuel usage. Did not Tracy have such a system?

If you place the regulator & its bypass prior to the flow sensor & injectors, you only need one sensor. The fuel 'dead heads' at the injectors, so it's always at full system pressure, and in the unlikely event that there is vapor in the lines, it's immediately blown through the injectors. It's how virtually every car is set up these days. It's being done in a/c, too. I'm pretty sure that Tracy has this fuel delivery architecture in the RV-8 3-rotor. >>> >>> If you're patient, you can find Flowscan sensors & various brands of totalizers on Ebay for very good prices. >>> >>> Charlie >>> >>> --- >>> This email has been checked for viruses by Avast antivirus software. >>> https://www.avast.com/antivirus >>> >>> >>> -- >>> Homepage: http://www.flyrotary.com/ >>> Archive and UnSub: http://mail.lancaironline.net:81/lists/flyrotary/List.html >> >> >> -- >> Homepage: http://www.flyrotary.com/ >> Archive and UnSub: http://mail.lancaironline.net:81/lists/flyrotary/List.html > > -- > Homepage: http://www.flyrotary.com/ > Archive and UnSub: http://mail.lancaironline.net:81/lists/flyrotary/List.html
