Been there, dun that. Too much hassle and resultant unreliability.
Jerry Davies, (Lyndhurst Touchdown Services) has developed a better system,
IMHO; the trouple with capacitance measurement is it never reads the same
twice, the dielectric constant of the fuel varies too much. Jerry uses a
magnetic float and a series of reed switches, so the reading is stepped, (8
or 10 steps) and therefore consistent. The switches are not submerged in
fuel, so safe.
