 N MPMS 7.4

Annotation

1.0 Scope

This standard covers the static determination of temperatures of petroleum and petroleum products in stationary aboveground bulk storage tanks using fixed automatic tank temperature (ATT) systems that include precision temperature sensors, field-mounted transmitters for electronic signal transmission, and readout equipment. This standard discusses temperature measurement in general, the requirements for custody transfer, and inventory control applications. It also discusses the requirements for data collection, transmission, and receiving. Appendix A of this standard describes local reading thermometers.

This standard does not cover the determination of temperature for hydrocarbons having a Reid vapor pressure above 15 pounds per square inch absolute (101 kPa).

Safety and material compatibility precautions should be taken into consideration when using fixed ATT systems. The manufacturer's recommendations on the use and installation of the equipment should be followed. Users of fixed ATT systems should comply with all applicable codes, regulations, and API standards and the National Electric Code (NEC).
