储罐底部锥体对计量的影响及减小偏差的方法

The Deviation Reduce Method and Effect of Tank Bottom Cone on Metering

对于储存成品油的储罐,罐底水尺处于非计量区时,液位变化将影响计量结果。通过对罐底锥体体积进行修正计算,可有效减小该非计量区的计量偏差,提高作业效率;对于罐底有水的成品油储罐,其库存量也将更加准确,有利于库存管。

When storage tanks for oil products, tank bottom water gauge in a non-metering zone, level changes will affect the measurement result. Through the tank bottom cone volume correction calculations, which can effectively reduce the deviation of the measured non-metered areas, improve operating efficiency： the bottom of the tank water of refined oil storage tanks, which will also be more accurate inventory, inventory management conducive.
