.13:2022 简化计量系统设计与基于绩效的方法论 非客户

[中文适用范围]： 本文件适用于单相气体计量，旨在指导用户在以下方面开展工作，以实现预定的测量不确定度目标：流量计量仪表类型的选择（包括差压式、容积式、超声波式、科里奥利式、涡街式、涡轮式、热式等）；用于测量流体性质及流动条件的配套仪表（如压力与温度变送器、密度计、气相色谱仪等）。 [外文原描述]： This document, for single-phase gas measurement, provides guidance in the following areas to allow the user to achieve a targeted uncertainty of measurement: selection of flow meter type: differential pressure, displacement, ultrasonic, Coriolis, vortex, turbine, thermal, and others; associated instrumentation for measuring fluid properties and flowing conditions, such as pressure and temperature transmitters, densitometers, gas chromatographs;
