The analysis of the gas flow meter scale measurement standard

Abstract: the analysis of gas flow meter scale measurement standard information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Gas measurement is, in fact, the gas flow measurement, it is in the process of gas flow of indirect measurement, measurement accuracy depends on the reasonable measuring system of a complete set of design, construction, operation and maintenance of the quality of the whole process. In order to guarantee according to the measurement system. More flow meter manufacturers choose model price quote you are welcome to inquire, the following is the analysis of gas flow meter scale measurement standard for details. Gas measurement is, in fact, the gas flow measurement, it is in the process of gas flow of indirect measurement, measurement accuracy depends on the reasonable measuring system of a complete set of design, construction, operation and maintenance of the quality of the whole process. In order to ensure metering system according to the unified technical requirements to conduct a comprehensive quality management, ensure the accuracy of gas amount of juice, formulate scientific and reasonable gas measurement standard is very necessary. In the natural gas metering standards, is the main flow metering standards. It also should include the gas density, composition, calorific value, the compression factor and other related parameters measurement and calculation of the standard, and instrumentation, such as design and safety standards. Gas measurement involves the design, construction, commissioning, operation, maintenance, inspection, verification and safety environmental protection and other aspects. Therefore, the relevant standard is very broad. There are strict perfect laws and regulations, standards and advanced measuring equipment. The United States in 1978 by the method of natural gas, natural gas prices, between United States and the federal government provides for per cubic foot of the actual energy content as the basis of natural gas business, changed the traditional natural gas metering. The quality of this new way of measurement is combined with natural gas and calorific value measurement two independent measuring systems and produce a new natural gas energy measurement system. 2, the ec gas metering standards of the European standard committee ( CEN） In 1998 a basic technical requirements of standard gas metering station NEN1776 ( GasSupplysystems - NaturalGasmeasuringStations - Functionalrequirement) 。 It includes a reference to the standard comprehensive comparison the ec gas measuring an overview of related standards. EN1776 gas metering station mainly include gas in the design, construction and putting-in-service proactively, operation and maintenance aspects of the basic requirements. Metering station capacity of flow rate is more than 500 m3 / h ( Standard state) , working pressure is not less than 1 bar ( Gage pressure) 。 Standard including energy units to the content of the settlement, it provides calorific value measurement method. Because of the metering station is composed of a variety of equipment, each kind of equipment to meet CEN standard hypothesis or ISO standards. In addition, the international standards for gas flow metering standards organization ( ISO) Technical committee also formulated a series of natural gas measurement standards and the suggestion. 3, our country natural gas metering standards of our country has not yet formed gas metering system standards. Domestic currently used in natural gas metering & other; Natural gas flow standard orifice measurement method & throughout; （ SY / T6143 - 2004). ，“ Natural gas calorific value, density, relative density and the calculation method for the wobbe index & throughout; （ GB / T11062 - 1998). Such as measurement standard. But these standard does not cover all aspects of the natural gas measurement, especially in the gas trade metering unified, lack of natural gas metering system of technical standards. In order to adapt to the needs of the increasing internationalization of China's natural gas, it is necessary to speed up with international standards of natural gas measurement standard. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.

This is an global standard which acts as a form of promise that Beijing Sincerity Automatic Equipment Co., Ltd manufatures according to the finest quality standards.
