一、概述在我国,多声道超声流量计尚未大量用于液态烃贸易计量,而在国外20世纪90年代末就已经开始应用,部分生产厂家在荷兰重量与计量部(NMI)、挪威石油董事会(NPD)等部门的监督下,在炼油厂和港口等原油及成品油管线上对其产品进行了长时间的性能测试,并取得了国际法制计量组织(OMIL)及NMI等的认证。为了追踪国外先进的计量技术,提升我国液态烃贸易计量水平,本文就FH8500型和1010S型多声道液
First, an overview In our country, multi-channel ultrasonic flowmeter has not been widely used in the measurement of liquid hydrocarbons trade, and abroad in the late 1990s has already begun to use some of the manufacturers in the Netherlands Ministry of weight and measurement (NMI), Norwegian Petroleum Board (NPD) and other departments under the supervision of the refinery and the port of crude oil and refined oil pipeline products for a long time performance tests, and has obtained the International Legal Metrology Organization (OMIL) and NMI certification. In order to track the foreign advanced metering technology, enhance the measurement of liquid hydrocarbon trade in China, this article FH8500 and 1010S-type multi-channel liquid
