From what others are posting it sounds like a calibrated dipstick, when used with a working clock and given a known fuel burn per hour based on experience, is a more dependable source of information, given the reliability of the sensor.  It's simply a reliable alternate source of information.

When I had the Tripacer I could estimate the fuel required to refill the tank after a two or three hour flight to within one or two tenths of a gallon.  That's close enough for my comfort given my personal reserve requirement and the $$$ needed to spend to get maybe 1/10 of a gallon more accurate.  A dipstick is not a joke, it's a tool.  It wouldn't surprise me if the caveman used a dipstick to measure the depth of the stream before crossing.
