Just getting around to reading old messages, and just a comment:  I have a Fuel Mizer, a relatively inexpensive fuel totalizer from Australia I purchased 2 years ago, and I have the sensor mounted just after the electric backup pump.  I do have a fuel return, and there is a calibration process that does the calculus on the non-linear relationships and is run over a long enough period to make it very accurate.  I would imagine your unit is equipped with similar software, in which case there would be no worries about inaccuracies arizing from the fuel return.

That particular option makes complete  sense, but would require altering the fuel plumbing on my aircraft, because the  fuel flow to the carburetors goes through a four-way splitter.  The  splitter gets the fuel from the pump on one leg, routes fuel to the carburetors  on two legs and has a restrictor in the fourth leg for the fuel return.   I'm trying to stick with the as-delivered kit components for now.   

  

 Based on the earlier replies, I'm planning to put the flow  sensor between the gascolator and the fuel pump, then calibrate the Dynon to  account for the fuel return.  The portion of the fuel going to the return  may not be a linear relationship, so the calibration remains uncertain, but  probably close enough for practical purposes.  I'll see how it  goes.

  

 I suspect the Brauniger flow sensor provides a pulsed output  like the Flowscan, but I don't know for sure.  As you suggest, I'll try  Dynon and see if they have the answer.

Jack,

  

 Thanks, that's good input.  I'm glad to hear that your  system worked through the calibration process OK.   As you say, I  suspect mine will do the same.  

  

 Paul
