For other liquefied gases modify the density defaults to their proper values in accordance with ASTM-IP Tables.

The EMR

calculates temperature compensated volume using the 12 density pairs from Table 4 above in the following
formula:
V
o
= V
t
(ρ
t
/ ρ
o
)
where: V
t
= uncompensated gross volume
V
o
= calculated temperature compensated volume
ρ
t
/ ρ
o
= ratio of density at measured temperature to density at base temperature
The ratio of density is calculated after inserting the appropriate P constants into the equation below:
ρ
t
/ ρ
o
= 1 + (-P

Notes:
The ratio of density is equation 4.21 from page 10 of the PTB-A 5 Measuring Systems for Liquids other than Water - June 1999 edi-
tion.
