摘要
针对原油流量检测要求快速、准确、数据量大等特点,将新型高速计数模块FM350-2应用到刮板流量计输出脉冲计数上,利用其无限循环计数和频率测量功能,并改进传统的数据处理方式,简化了瞬时流量和累积流量的计算,提高了检测的实时性和准确性。
Considering the fact that oil flow rate detection requires quick speed,preciseness and mass-data,the system for oil flow rate detection based on FM350-2,a new high-speed counter applied to counting of the pulse of the scraper flowmeter,was proposed.The system can simplify the calculation of both instantaneous and accumulative flow by making use of unlimited cyclic counting and the frequency measurement.The running results prove the success of system in precision measurement,fast reaction and without accumulative error after a long time running.
