Abstract： Metering pumps are widely used in fluids industry. Current researches often focus more on international structure improvement and design of automation systems，while lacking on remote monitoring and coordination of pump groups. Aiming that the metering pumps typically cooperate to work in industry，an improved plan of metering pumps networking monitor solution and appropriate commniucation method was presented to meet the needs of large-scale monitoring. A Java based data server was designed to manage data in monitoring system. To solve the problem of system performance degradation，a scheme of ring object pool was put fowward，based on ring cache mechanism. Finally， different conditions and testing network delay time were simulated. Results indicate that the server can ensure data real-time and reliable，and can be used in large-scale metering industrial monitoring.
