Fuel flow change

Postby JimB » Mon Jul 08, 2019 12:54 pm

I have two Flo Scan transducers for fuel flow, one measures in the other out. It’s worked ok for many years. This season it seems to be about 15% low. The only change was that the engine was off the airframe this winter but all lines were capped.

Looking for suggestions on what to check, clean etc? Is best way to clean is by flowing in reverse? I did check that flow is zero with pumps on and fuel flowing but engine not running. I think that means the return sensor is ok.

Thanks

Just an update. I cleaned both FloScans by reversing the flow, ie put the in hose on the out connection and ran fuel thru them for a few minutes. I tried to run the fuel thru a paper towel to see if there was debris but that wasn't very obvious. But after doing this to both FloScans, my fuel flow in operating normally.
