Friend just tell me about fuel flow

Friend just tell me i installed ft 60 fuel flow tranducer on aircraft after two month they becom us i mean when i put auxiliary fuel on they give .6 fluctuation

Be sure the red cube is installed per instructions (away from the pump). On injected engines, it is usually installed between the fuel servo and flow divider.

what is important in resolving the air bubbles is that there is a 1-2 inch lift in the fuel line after leaving the transducer, going down causes air to remain within the red cube and it would cause the fluctuations. The boost pump is forcing fuel and any air through, going up should force it away from the cube not effecting the fuel flow reporting.

Call EI support, they are really good and can help troubleshoot your issue.
I don’t have any fluctuations at idle, nor should you.
the other plane, same location and setup? you Know the red cube is working than so it’s something with your location or way it’s setup. Make sure the wires are facing up, that has been known to result in issues.

I moved your question to a new thread so readers can identify your issue and assist. Otherwise they will think this is another response to the red cube issue.
