标准范围
本文件规定了在封闭管道中测定常规流量体积流率的方法a) 指密度基本恒定的流体,或对应于不超过0.25马赫数的流体,b) 测量横截面上的停滞温度基本均匀,c) 在管道中满负荷运行d) 在稳定流动条件下。特别是,它涉及皮托静压管的技术和维护,根据测量的压差计算局部速度,以及通过速度积分计算流量。
This document specifies a method for the determination in a closed conduit of the volume rate of flow of a regular flowa) of a fluid of substantially constant density or corresponding to a Mach number not exceeding 0,25,b) with substantially uniform stagnation temperature across the measuring cross-section,c) running full in the conduit, andd) under steady flow conditions.In particular, it deals with the technology and maintenance of Pitot static tubes, with the calculation of local velocities from measured differential pressures and with the computation of the flow rate by velocity integration.
