Ah Gordon I'm much relieved it wasn't a simple answer as I thought might have missed a basic thing I should have known. Yes that's a very comprehensive link.
You're close but its not quite a distance thing in itself. Perhaps the full view will help.
So you are there Bernard I thought it was unlike you to miss a MO. I assumed you must have been outdoors sipping tonic water under a sunshade.
I'd like to say yes but I'm afraid its not quite the answer I was hoping for
Gordon what is an ACCO?
Yes one of the functions of the contrivance is to measure distance, others said it was a speedo but its not a speedo.
I think you are nearly there Gordon can you just clarify your answer please.
A good suggestion Derek. Certainly not complimentary but not quite accurate as this is not not so much about measuring fuel but taking samples. Except rurally here the samples tend to be quite large :-(
Nope I don't think you would like it if I called you this name. You've won anyway, but for completeness I was hoping someone would get the official name that is an every day noun. It is not in some fancy service nomenclature.
