【Abstract】 In order to improve the accuracy of the measurement instruments of three phase flow of oil, gas and water, a calibration system is designed for them. The principle and constituent of the system are presented. The main accuracy specifications of the system are ±0.2% for liquid, and ±1.5% for gas. The water containing in oil is less than 1% when oil, gas and water are separated.更多还原
