摘　　要：在流量参数量值传递过程中,存在着质量流量和体积流量的相互转化,而二者的转化过程中最主要的影响因素便是介质的密度,在流量标准装置中介质密度的最大影响因素便是工作温度。为了更好地保证流量参数量值传递的准确可靠,介质密度随温度的变化就需要额外被重视,通过温度监测去监控介质密度是实现流量参数量值输出准确的重要途径。这是产业发展的要求,也是传统计量向产业计量转型和国务院发布的《计量发展规划(2013—2020年)》的要求。There are mass flow rate and volume flow of mutual transformation in the process of dissemination.Density is the influence factors of the transformation.Medium density in the flow standard device one of the biggest factors is the working temperature.Medium density with temperature change is need extra attention in order to better ensure traffic dissemination of accurate and reliable.Through the temperature monitoring to control medium density is an important approach to realize the flow rate of the metrological.This is the requirement of industrial development.This is the requirement of traditional metering to industry metrology transformation.This is the requirement of metrology development plan(2013-2020).
