铂电阻温度计在成品油公路付油系统中的应用

Application of Platinum Resistance Thermometer in Highway Oil Products Delivery System

针对成品油油库公路付油过程中因油品温度变化引起的油品体积变化,从而影响实际付油精度的问题,提出在付油管路中流量计前加装高精度铂电阻温度计与温度传感器连接,即时采集付出油品的实时温度,通过逻辑分析判断,引用车用汽、柴油各自油品膨胀系数或内嵌《石油计量表》(GB1885),实时计算并修正自动付油程序中的付油量,可提高付油精度。四座油库运行的数据表明,付油准确度保持在0.1%以内,大大低于容积式流量计本身0.2%的准确度等级。

According to the problem existing in the highway oil products delivery process that the accuracy of the actual oil delivery could be affected by the volume changes,due to the oil temperature variation in the process of oil delivery,the installation of high precision platinum resistance thermometer in oil pipeline was proposed by which the real-time temperature of oil product could be collected. Through the logical analysis judgment,citing the expansion coefficient of vehicle gasoline and diesel or the embedded ' Petroleum Measurement Tables( GB1885) ',the oil delivery amount could be corrected immediately in the automatic oil delivery process,so as to improve the oil delivery accuracy.
