h
hh h is the height of the nozzle. dddd is the diameter of the tank nozzle.
INFORMATION!
• If h < d, then the top dead zone (A1) is equal to the top dead zone for the probe only. Refer to
the table that follows.
• If h ≥ d, then the top dead zone (A1) is equal to the tank nozzle height plus the top dead zone
for the probe.
