GENERAL.
The cylinder
head temperature
gauge
is in the
instrument
cluster,
located
on the
instrument
panel.
This instrument
measures
the cylinder
head
temperature
using
a sender
located
in a cylinder
head.
The head
location
is determined
by
the engine
manufacturer.
It is an electrical
instrument
and is wired
thru the
instruments
circuit
breaker.

FUEL
FLOW
GAUGE.
10-89.
GENERAL.
The fuel flow
gauge is
a non-electric
pressure gauge
mounted
in the
bottom
half of
the manifold
pressure gauge
located
in the lower
portion of the
instrument
panel.
On PA-32RT-300
this
instrument
measures
flow by
reading
the pressure
drop
across a
fixed
orifice
located
in the fuel
divider.
With a constant
fuel
pressure
being supplied
by
the
engine
driven
pump,
and putting
a fixed
orifice in
the fuel
divider head,
and then
measuring
the pressure
drop
downstream
of
the orifice
against
a constant
static pressure,
the
resultant
pressure
can be
calibrated
in gallons
per hour
flow.
The constant
static
pressure
is supplied
by a vent
line running
to the
engine compartment.
The vent
line to
the engine
compartment
automatically
compensates
the instrument
for
altitude.
On
PA-32RT-300T
this
instrument
measures
flow
by reading
the
pressure
differential
between
the
deck
pressure
and
metered
pressure
to
the fuel
nozzles.
The
pressure
differential
is
calibrated
from
the engine
manufactures
data
to result
in a readout
of gallons
per
hour
flow.
