移动式天然气流量计量橇(以下简称“计量橇”)是一项专业性强、技术难度大、带有科研性质的工程项目,是目前国内唯一一套自主设计、投资、成套制造的高压、大流量和高准确度的移动式天然气流量计量橇,填补了国内空白,整体技术处于国内领先水平。为国家石油天然气大流量计量站实现今后对国内天然气流量计进行现场实流检定和计量仲裁提供了条件。一、技术方案1.总体结构根据目前国内在用天然气流量计的压力等级、口径、流量范围和准确度等级,考虑到计量橇的运输和吊装方便性,在总体设计中,要求计量橇的尺寸小和重量轻,能对DN300超声波流量计进行全量程检定。
Mobile natural gas flow measurement sledge (hereinafter referred to as “measurement sled”) is a professional, technical difficulty, with scientific research projects, is currently the only set of independent design, investment, package manufacturing High pressure, high flow and high accuracy of mobile natural gas flow measurement sled, to fill the gaps in the country, the overall technology is at the leading domestic level. It provides the conditions for the national oil and gas large flow metering station to realize the on-the-spot flow verification and measurement arbitration of the domestic natural gas flow meters in the future. I. Technical Solution 1. Overall Structure According to the pressure level, caliber, flow range and accuracy grade of natural gas flow meters currently in use in China, taking into account the convenience of transportation and lifting of the measuring skids, in the overall design, the size of the measuring skids is required Small and light weight, can DN300 ultrasonic flowmeter full scale test.
