a device that automatically converts the volume measured at metering conditions into a volume at base conditions or into a mass, by taking account of the characteristics of the measured liquid (temperature, pressure, density, relative density, etc.) using associated measuring instruments, or associated values stored in a memory. The quotient of the volume at base conditions, or of the mass, to the volume at metering conditions is referred to as the “conversion factor”
