Gas Monitoring and Instrumentation Standards

Gas Monitoring and Instrumentation Standards describe general practices for sampling, measuring, and monitoring various gases in the environment. Through the establishment of uniform instrumentation techniques for the efficient analysis of gaseous effluents, standardization of analysis and reporting methods is made possible. These guidelines facilitate the examination of health safety issues associated with the reduction of radioactive emissions and enhancements to greenhouse gas removal, as well as providing several detailed solutions to these problems. In addition, the standards address various types of gas testing, such as leakage measurement, exhaust gas emissions, radioactivity of gaseous effluents, greenhouse gas emissions and more. AGA Gas Measurement Manuals provide guidelines for use of specific instruments vital to the process of gas measurement and monitoring.

American Gas Associations' Gas Measurement Manuals

The American Gas Association’s Gas Measurement Manuals provide a comprehensive outline of the gas measurement industry. These standards include a brief history of gas measurement, descriptions of the most salient business practices and theories of operation, as well as a lengthy glossary of terms. Optimal practices for the selection, installation, and maintenance of measurement and monitoring equipment are provided; the use of inferential, orifice, displacement, and turbine meters are presented. Guidelines for sampling and analyzing gases, varying computation techniques, and the methods of identifying specific gas properties such as gravity, heating value, moisture content, sulfur, temperature, pressure, supercompressibility, density, total composition and proper odorization are featured.

Greenhouse Gas Monitoring Standards

Greenhouse Gas Monitoring Standards address the measurement and reporting techniques dealing with greenhouse gas emissions. Methods of design, development, and administration of reporting techniques, principles of data assessment, and extensive testing and verification of assertions are the focal points of these standards. Included here are recommended practices for the enhancement of greenhouse emission reduction and removal, as well as the planning and management of greenhouse gas projects involving the identification of greenhouse gas sources, sampling and monitoring of gas emissions, and the reporting of greenhouse gas inventory.

Chemical Gas Monitoring Standards

Chemical Gas Monitoring Standards address techniques for the continuous measurement and analysis of chemical gas emissions. The specification of recommended selection, design, manufacture, and certification of measurement instrumentation and methods of application is included. Furthermore, these standards outline the main principles concerning the measurement of radioactivity in discharged gaseous effluents, those present in the environment itself, and those found in the workplace. Acceptable procedures applicable to gas measurement through aerosol effluent, noble gas effluent, iodine, and tritium monitors are included.
