TEMPERATURE COMPENSATION METHOD - COEFFICIENT OF EXPANSION
Temperature compensated volume changes for specific products are determined using the formula:
V
o
= V
t
+ V
t
[C
oe
(15°C - t)]
Coefficient (C
oe
) values may be modified to meet specific fuel/product specifications. The factor “t” is the
measured fuel temperature. For example, use the procedure described in Figure 40 on page 39 to change the
default coefficient of expansion for diesel from 0.00081 to 0.00083. To calculate temperature compensated
volume the coefficient of expansion (C
oe
) is now equal to 0.00083.
