Floscan problem

[malko05]

Hello,

I have a problem with the fuel flow (D180 and FloScan).
It worked perfectly for 150 Hours. During the last flight, he began to read 0, by intermittently, then more, then 0 all the time.
The electrical circuit seems in good condition, is there a way to test (a value measured at the output of the probe) before buying a new sensor? It seemed to me that these probes are very reliable!

Not trivially. You might check for debris that may have stopped the impeller (but isn't stopping the fuel flow). Beyond that, make sure that all 3 of the wires have continuity to the places they're supposed to go.

I found the problem. These air bubbles!!
I put the output of the FF to a can, put the electric pump, I tap the FF, and since it works! Already 7 hours of flight and no more problem.

Thank you anyway...
