This chapter describes the methods, equipment, and procedures for manually determining the temperature of liquid petroleum and petroleum products by use of a portable electronic thermometer (PET). This chapter discusses temperature measurement requirements in general for custody transfer, inventory...

This Standard applies to thermowells machined from bar stock and includes those welded to or threaded into a flange as well as those welded into a process vessel or pipe with or without a weld adaptor. Thermowells manufactured from pipe are outside the scope of this Standard....

This section describes how to correctly use various types of liquid-in-glass thermometers to accurately determine the temperatures of hydrocarbon liquids. Other methods, equipment, and procedures for temperature determination are described in the other sub-sections of API MPMS Chapter 7. This...

This Practice provides engineering guidelines for the selection and application of temperature measurement instrumentation. This Practice describes the requirements for selecting thermocouples, resistance temperature detectors, thermowells, thermistors, pyrometers, filled thermal systems,...

This International Standard describes the requirements for thermocouples suitable for nuclear power plant (NPP) applications. Thermocouples are widely used in NPPs with other temperature measurement devices such as Resistance Temperature Detectors (RTDs). They are simple and robust and have some...
