Abstract: IN the course of the last 10 years, measurement has undergone certain farreaching changes that have been marked by the increased employment of technical people in the measurement departments of the many utilities and associated manufacturers. Some of the influencing factors and activating forces which are contributing and causing these changes are the following: 1. The availability of high-speed programmed desk calculators and the ever increasing use of computer systems has released this technical capability, to a large degree, from the tedious calculations normally required to calculate flow, As a consequence, more time is placed on the scrutinizing and examination of output data, thus emphasizing results. 2. New computer statistical techniques and advanced technology in fluid mechanics have been applied to present metering systems and their associated formula. In some instances these statistical techniques have revealed discrepancies in formula and metering devices which heretofore have gone unchallenged. Monies have been allocated by the gas industry to various research institutions to investigate these uncertainties and to propose more accurate methods of measurement. 3. Another facet of major importance is that industries associated with the gas industry are placing more instruments and devices on the market than has been available in the past 20 years. Some of these devices incorporate the latest advancements in technology that have been proven accurate and reliable. 4. Many new measurement concepts are being introduced by companies not closely related to the gas industry. These concepts are a spin-off of government projects and company research programs. 5. Several gas companies have built test facilities where new measurement devices can be evaluated and their performance characteristics ascertained. In many cases this information provides the manufacturer with technical data that would otherwise be unobtainable. Also this performance data is used by the gas company as a basis to gain acceptance and approval of the new metering device. Apart from the technical advantages offered by these facilities, their very existence instills a certain discipline into the market by preventing the widespread use of equipment that may prove to be unsatisfactory, despite the assertions presented by the manufacturer.
