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.
