摘　　要：针对联合站原油储罐因加药量、加热温度控制不合适而导致过渡带太厚、盘库不准等现象,研制一种原油储罐全程含水分析仪,开发同时具有超声波、温度两种传感器的多功能信号采集装置,整合含水率、液位、界面和温度测量功能于一体。该设备由信号采集装置、电动机驱动装置、PLC和上位机四部分组成,利用超声波反射原理,判断储罐内不同层位的含水率,把信号采集装置数据与编码器数据通过上位机整合后形成储罐内的液位、界面,并把含水率、温度数据传送到监控室的上位机,含水率检测误差小于或等于2%。通过该设备对原油储罐不同层位含水率、温度的准确检测,可优化加热、加药方案,节约成本。Because of improper dosage and heating temperature of the crude oil storage tanks in multipurpose stations,the filter strip is too thick and the stocktaking is not accurate. Aiming at the problem, a whole- course water content analyzer for crude oil storage tanks is developed, and a multi- function signal acquisition device with both ultrasonic and temperature sensors is developed, which integrates the water content, liquid level, interface and temperature measurement functions. The device consists of the signal acquisition unit,the motor driving unit,PLC and the upper unit,using ultrasonic reflection principle to judge the water content in different layers inside the tank. Finally,the data of signal acquisition device and encoder are integrated by the upper machine to form the liquid level and interface within the tank,and water content and temperature data are transmitted to the control room of the upper machine. The detection error of water content is no greater than 2%. The accurate detection of the device for the water content and temperature in different layers in crude oil storage tanks can optimize heating and dosage schemes and save cost.
