the problem with him. No one had any great ideas - the only thing we could
come up with was a fuel starvation - maybe from the Vision Micro fuel flow
sensor (it has a restrictor in it).
Thursday morning we removed the VM flow meter and reconnected a straight
Matt,
I was sorry to hear about what happened on your flight. I read what happed and just wanted to address the comments you had mentioned above regarding the VM flow meter.
The flow transducers that are manufactured for us are certified and are also used by virtually all other manufactures of fuel flow instrumentation. You mentioned that the flow transducer has a restrictor in it. The flow transducer 'restriction' is really a flow director and represents very little pressure drop. It is used on very high flow rate engines (>30gph).
The pressure drop (as published by transducer mfg.) for gasoline is nonlinear and is as follows:
30 GPH ~1.2 PSI
15 GPH ~0.3 PSI
7 GPH ~0.1 PSI
