IS 15674: 2006 Flow measurement of natural gas by ultrasonic meter

In English.
Number of pages: 20.This Indian Standard was adopted by the Bureau of Indian Standards, after the drafl finalized by the Weights and Measures Sectional Committee had been approved by the Production and General Engineering Division Council.This standard is taken for measuring the gas consumption at the bulk suppliers as well as at the users’ end, when the gas is supplied through the pipelines. In order to meet the requirement of bulk supplier and large consumer, Bureau of Indian Standards has formulated standard for accuracy of metering system and regulation of gas at different delivery point to fulfill the consumer satisfaction as well as financial help of the organization. This standard is basically a performance-based specification of Multi path Ultrasonic Meters and should meter exceed the accuracy, functional and testing requirements. The users should follow the applicable installation recommendations as indicated in this standard.In preparing this standard considerable of assistance has been taken tlom the following publications:
- ISO/CD 17089 Measurement of fluid flow in closed conduits — Ultrasonic meters for gas.
- ISO/TR 12765:1997(E) Measurement of fluid flow in closed conduits — Methods using transit time.
