This is a generic topic, not specific to Dynon products.
I would like to start a discussion on the benefits of having a fuel pressure indicator when a fuel flow indicator is already installed.
Many airplanes have fuel pressure indicators or fuel flow indicators, but not that many have both. Some use fuel pressure to deduce fuel flow and display the reading in gph, not psi.
I am adding a (non-Dynon) EMS to my Twin Comanche and the system did not come with fuel pressure senders but those can be added for an additional price. The original airplane used pressure converted to flow. It was modified with a Shadin system that actually measures flow and the old pressure system was removed. The new Auracle system uses flow meters for fuel flow like the Shadin.
So, what would be the benefit, if any, of adding the optional fuel pressure system? I don't see much benefit of knowing pressure if I know fuel flow. Please tell me if I am missing something.
FWIW, the sales guy from the other company is actually discouraging adding the optional fuel pressure sensors since the TC for the PA30 doesn't require it (true) and fuel flow is included.
