验证流量计的目的是确定其相对误差或流量计系数，作为流速和其他参数（如温度、压力和粘度）的函数。使用的验证系统类型如下:储罐校准系统；双向和单向管道校准器；主仪表。它们可以连接（固定或移动）到计量站或在中央试验站中使用。

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.
