摘要
总结了国外对液化天然气流量计标定研究的现状,结合国际液化天然气进口商组织贸易交接计量手册和主流液体超声波流量计的现场应用,对比液化天然气输运船舱液位测量与液体超声波流量计在液化天然气体积测量方面的准确度;简要介绍国外计量机构对液化天然气动态计量标定装置的研究现状,以及德国KROHNE Altometer的计量表和美国CAMERON公司的Caldon液体超声波流量计在国外液化天然气接收站中作为比对计量表和内部分配计量表的应用情况。同时结合国内对液化天然气计量的需求,分析了国内液化天然气动态贸易交接计量研究的方向。
The study on calibrating the LNG flowmeters abroad were summarized; basing on the custody transfer measurement manual from the international LNG importers and the field application of ultrasonic flowmeter,the accuracy of applying a level meter to measuring the volume of ship's tank and that of employing a ultrasonic flowmeter to measure the ship tank's volume were compared,including the application of KROHNE Altometer and CAMERON Caldon liquid ultrasonic flowmeter in LNG receiving stations both at home and abroad. The study direction for home LNG's dynamic custody transfer measurement was analyzed.
