标准摘要
[中文适用范围]： 本文件描述了通过管道中安装的压力传感器测量流体中的声速的测定程序。该文件适用于所有类型的液压回路，在稳态条件下运行，无论大小如何，针对频率范围从10 Hz到3 kHz的压力脉动。 [外文原描述]： This document describes the procedure for the determination of the speed of sound in a fluid enclosed in a pipe, by measurements from pressure transducers mounted in the pipe. This document is applicable to all types of hydraulic circuit operating under steady state conditions, irrespective of size, for pressure pulsations over a frequency range from 10 Hz to 3 kHz.
