标准范围

本文件规定了测量液压流体动力导管中平均稳态压力的程序。适用于测量内径大于3mm的封闭管道中的平均稳态压力，输送平均流速小于25m/s、平均稳态静压小于70MPa的水力。它不适用于与封闭流体导管壁齐平安装的传感器，或封闭流体导管壁不可分割的一部分。它提供了估算给定压力测量中总不确定度的公式。

This document establishes procedures for measuring the average steady-state pressure in a hydraulic fluid power conduit.It is applicable to the measurement of average steady-state pressure in closed conduits with inside diameters greater than 3 mm, transmitting hydraulic fluid power with average fluid velocities less than 25 m/s and average steady-state static pressures less than 70 MPa.It is not applicable to sensors which are flush mounted with, or an integral part of, the closed fluid conduit wall.It provides the formulae for estimating the total uncertainty in a given pressure measurement.
