Cubical coefficient of expansion is out of range for API 54C.
To obtain the net volume of liquid at 15°C, multiply the uncompensated meter reading by the Volume Correction Factor (VCF) which corresponds to the average measured temperature of the liquid during the delivery.
Densities are mass (in vacuum) and are taken from: Thermodynamic Properties of Ammonia, by L. Haar and J.S. Gallagher, Journal of Physics Chemistry Ref. Data, Vol. 7, No.3, 1978.
