The
most
frequent
delivery
termination
is
during
filling
the
full
storage
tank
when
the
gas
flow
rate
drops
under
the
set
value
(4)
at
dispensers
without
temperature
compensation
and
delivery
termination
by
attaining
the
maximum
possible
gas
mass
calculated
by
temperature
compensation
(5).
In
both
cases
delivery
termination
is
signalled
by
the
“FULL”
message
on
the
product
unit
price
display.
Delivery
is
finished
by
hanging
the
delivery
nozzle
to
the
dispenser.
NOTE
Delivery
with
temperature
compensation
performed
so
that
the
dispenser
shall
verify
the
situation
in
the
vehicle
storage
tank
by
a
small
amount
of
gas
at
the
beginning
of
delivery
and
calculates
the
maximum
gas
mass
which
it
is
able
to
deliver
under
given
ambient
temperature.
After
attaining
the
maximum
mass,
it
finishes
the
delivery
and
shows
the
“FULL”
message.
According
to
technical
rules
of
TPG
304
02
art.
4.5.4
the
limit
values
in
the
Czech
Republic
for
calculating
maximum
gas
mass
in
the
vehicle
are
as
follows:
a)
maximum
gas
pressure
converted
to
15
°C
–
20.0
MPa
b)
attain
maximum
overpressure
in
a
vehicle
26.5
MPa
c)
attaining
maximum
gas
temperature
in
a
vehicle
82
°C
NOTE
According
to
ISO/DIS
16923,
par.
7.5
CNG
dispensers
must
be
equipped
with
a
breakaway
coupling
located
between
the
delivery
nozzle
and
the
dispenser.
This
breakaway
coupling
disconnects
the
gas
flow
rate
at
both
ends
in
case
of
emergency.
The
force
that
causes
breaking
the
coupling
must
be
higher
than
220N
and
lower
than
600N.
OCEAN
CNG
dispensers
are
standardly
equipped
with
a
breakaway
coupling
with
a
magnetic
sensor
of
breaking.
After
breaking
the
hose,
the
delivery
is
immediately
terminated
(magnetic
valves
are
closed)
and
the
display
shows
the
error
message
E67.
