Please don't regard him as an "expert"; he's getting quite old and thinks that "fadiddling fumble-putz" is a more accurate description.

    Let’s hear it for good old sight glasses.

    While sight gauges are pretty foolproof and reliable, they’re mighty tough to monitor from the helm station. I’d welcome the availability of what sounds like a simple to install, flexible to monitor probe like this – and capacitance fuel level sensors have a long history of accuracy & reliability in aviation, though there are some issues relating to calibrating the unit to match the density of the specific fuel type.
    I agree with Ben’s concerns about using this type of probe to sense fuel contamination however.

    This tech is the same as, they have sold cap guages for some time.
    Proven tech. used in industrial field form the 80’s

    The capacitive probes measure the dielectric properties of the fluid, not the density.

  5. Norton Rider says:

    The fuel quantity in large aircraft is measured in pounds or kilograms, not volume. This is where the calibration R.O. is referring to comes in.
