Fuel Flow flucuates

[ddddsp]

Recently I noticed my fuel flow is now fluctuating. For the past 400 hours is was very steady now it seems to vary about 1-1.5 GPH on the reading. I have a Floscan in my RV10 carb O540.
Is there something I should check or is there an issue with my Dynon?

First place I'd look is for air trapped in the Floscan. The outlet side needs to be higher than than the inlet to ensure any air flushes.

That definitely sounds like a sensor air or debris contamination sort of an issue. Could be an intermittent electrical connection, but given the nature of that input, probably isn't the Dynon unit itself.
