摘要
水蒸气含量／水露点是天然气一项重要的气质指标，随着天然气国际贸易量与日俱增，其测定方法和仪器的标准化已在全球范围内引起普遍重视。文章从方法原理、仪器选择、操作评价、取样与安装、仪器的校准、检验与维修要求等方面，介绍了可应用于在线测定的电容式、电导式、压电式、光学式和红外式等５类测定仪器的特点及测定范围。建议我国应组织力量，在与国际接轨的基础上，加快此类仪器标准化的进程。
Water content/water dew-point is an important quality index of natural gas. With increasing international trade of natural gas, the standardization of its determining method and related instrument is emphasized globally. According to the feature and measure range of five kinds of instruments (capacitance, piezoelectric, conductivity, optical and infrared models), this paper introduces the working principle, operation evaluation, sample, installation, calibration, inspection and maintenance of the instruments. This paper also suggests that the standardization of the instrument should be set up on the basis of matching with international standard as soon as possible.
