For the problems of the complicated installation and removal of dynamometer card detection equipment, high cost, not convenient for real-time detection, prone to failure and maintenance workload, a kind of low cost wireless dynamometer is developed. With the implement of wireless transmission gateway, comprehensive monitoring software is programmed. This system consists of a pumping dynamometer, gateway, monitoring software and indicator diagram measuring algorithm. Finally, the wireless dynamometer was installed at RenQiu oil field, and the data shows that the system works well and can be used for the long-term working and operating state of pumping oil field monitoring.
