Liquefied Petroleum Gas Liquid-Measuring Devices Seminar


This 5 day seminar will teach students how to properly inspect and test LPG metering systems, i.e., perform an official examination by properly applying all applicable NIST Handbook 44 requirements, which are outlined in NIST EPO 26. The sessions will include formal lecture, class discussion, group exercises, audio-visual presentations, and some hands-on practice.  

Learning Objectives:

After this seminar, participants will be able to:

  • IDENTIFY and DESCRIBE the major types of metering systems used for commercial measurement and delivery of LPG liquid;
  • DESCRIBE the design and operation of typical metering systems and their major components, especially those involved in measuring, indicating, recording, and delivering product;
  • DESCRIBE and APPLY basic safety procedures and equipment, including emergency procedures, employed in examining LPG liquid-measuring systems;
  • IDENTIFY appropriate test equipment used for testing these metering systems in the field and describe procedures for setup, operation, and maintenance of this equipment;
  • DESCRIBE procedures for inspecting LPG metering systems to determine whether they conform with specifications and other requirements set forth in NIST Handbook 44, and in accordance with NIST Examination Procedure Outlines for Weighing and Measuring Devices;
  • DESCRIBE procedures for testing these metering systems in the field to determine whether or not they conform to performance requirements set forth in the latest edition of NIST Handbook 44, “Specifications, Tolerances, and Other Technical Requirements for Weighing and Measuring Devices;” and
  • DESCRIBE post-examination tasks that must be performed upon completion of an official field examination, including documentation and recordkeeping.

Technology Requirement(s):

Participants MUST bring a calculator. 

Materials & Supplies:

Notebooks and class materials will be provided.


Participants must have completed the Handbook-44 Self Study (http://www.nist.gov/pml/wmd/lmdg/training-materials.cfm)
