The above drawing is a schematic of fuel
gauge
wirinb The internal
tesistanoe value
of the gauge
unit is adapted to vary with the
height of the float- It is mcult for m e n t
to pass through the circuit when the
resistance vaIue is high, an
consequently
the
swing of
the
meter is
m a l l
(close to point
E l .
The more current passes through the circuit,
increasing
the
swing of the pointer (close to
point F), when the resistance value i s low.

relationships
between the
amount of
gasohe and

indications are

Main operation
Current passing through the heater wire
deflects the main bimetal causing the pointer
to
move.
m
Auxiliary operation
This compensates for variations in
temperature
and
voltage. A temperature
cornpensating bimetal
is
provided
so that no
indication
errors occur due to temperature
changes inside the
meter:
The meter
points to
