摘要
油田水中含有大量的碳酸根和碳酸氢根 ,介绍采用双电极法测定的原理和方法 ,并研制基于该法的自动测定系统。测试系统以单片机为核心进行控制和信号处理 ,放大电路实现高阻抗匹配和信号放大 ,温度补偿电路实现温度的自补偿。系统具有性能可靠、测量速度快、测量范围宽、可长时间连续使用和在线测试的特点。
There are many carbonate and bicarbonate in oil field water.Coupled Ion-Selective electrode measurement of carbonate ad bicarbonate is introduced.The inetlligent system based on the method is develcoped.The design is based on single board computer which implement the processing and controlling of signal.The function of circuit is to realize high resistance matching and amplify signal and temperature compensation.The instrument has advantages of reliability,quickness,big range and can work for a long time and on line.
