Research of Zigbee Based Oil Field Intelligent Flowmeter

Change the flowmeter＇s structure to improve the measurement precision and accuracy based on its traditional measurement principles. Zigbee wireless short transmission technology was applied to oil field flow data monitoring. Cluster （tree） network was established. In addition to this, two working modes were designed for the network. Periodic Mode and Interrupt Mode. Experimental results show that the system had good linearity, and transmission error would be controlled under 3 percent. It also shows that the wireless transmission link is reliable and owns the ability of self-repairing. The research of Zigbee Based Oil Field Intelligent Flowmeter is of great significance to the real-time monitoring of oil flow rate.
