标准摘要
[中文适用范围]： 检验仪表的目的是确定其相对误差或其仪表系数作为流量和其他参数（例如温度、压力和粘度）的函数。 正在使用以下类型的证明系统： 储罐证明系统；管道检验仪，双向和单向；主米。 它们可以连接（固定或移动）到计量站或中央检验站中使用。 [外文原描述]： The purpose of proving a meter is to determine its relative error or its meter factor as a function of flow rate and other parameters such as temperature, pressure and viscosity. The following types of proving systems are in use: tank prover systems; pipe provers, bidirectional and unidirectional; master meters. They can be used either connected (fixed or mobile) to the metering station or in a central proving station.
