The calibration accuracy of skid-mounted piston volume tube is influenced by many factors such as the bump of launch vehicle traveling process, the complex composition of crude oil medimn. The effects of the influencing factors on the metering perfor- mance of the skid-mounted piston volume tube are analyzed in order to improve the calibration accuracy of crude oil flowmeter. The necessity and the selection of the calibration methods of intermediate checks of the skid-mounted piston volume tube are discussed according to the working principle of the volume. The implementation of the intermediate checks is expounded, and the intermediate checks of three in-use skid-mounted volume tubes are implemented, which can ensure the stable operation the accurate and reliable test data of the whole device, and can reduce metering disputes and ensure the accurate and reliable value transfer of crude oil flow- rate in oil fields.
