摘　　要：液氢是超低黏度、超低密度的低温流体,流量计检定采用水等其他流体替代时引入的误差大。因此,发展用于液氢流量计实流检定的液氢流量标准装置非常必要。本文归纳了当前国内外仅有的低温流量标准装置的测量原理、结构组成和功能特点。基于静态质量法设计了一套液氢流量标准装置,并探讨其工艺流程和可行性,为构建液氢质量流量标准和完善氢流量计量体系提供技术参考。Liquid hydrogen is a cryogenic fluid of ultralow-viscosity and ultralow-density.The error introduced by the replacement with other fluids such as water in flowmeter verification is large.Therefore,it is necessary to develop a liquid hydrogen flow standard device used for the actual flow verification of liquid-hydrogen flowmeters.This paper summarizes the measurement principle,structural composition and functional characteristics of the few low-temperature flow standard devices around the world.A set of standard liquid hydrogen flow rate device is designed based on the static mass method,and its technological process and feasibility are discussed.This review can be helpful to build liquid hydrogen mass flow standards and improve hydrogen flow measurement system providing technical support.
