标准摘要
[中文适用范围]： 本国际标准规定了在下列条件下使用螺旋桨式流量计通过速度面积法测定封闭管道中体积流量的方法： a) 速度分布规则（见 6.1.1）。 2）； b) 流体是清洁的或被认为清洁的水1)； c) 导管已满； d) 流量稳定2)。 它特别涉及螺旋桨式电流计的技术和校准、局部速度的测量以及通过速度积分计算流量。 [外文原描述]： ISO 3354:2008 specifies a method for the determination of the volume flow-rate in a closed conduit by means of the velocity-area method using propeller-type current-meters under the following conditions: a) the velocity distribution is regular; b) the fluid is water which is clean or considered to be clean; c) the conduit is full; d) the flow is steady. ISO 3354:2008 deals in particular with the technology and calibration of propeller-type current-meters, the measurement of local velocities and the calculation of the flow-rate by velocity integration.
英文名称Measurement of clean water flow in closed conduits — Velocity-area method using current-meters in full conduits and under regular flow conditions
