摘　　要：压力传感器的精度对油罐自动计量系统的精度起决定性的作用。每套油罐自动计量系统客观存在着保证测量精度的最小测量高度,油罐内所装油品高度低于最小测量高度时,油罐自动计量系统的计量误差有可能大于预定误差。The accuracy of oil tank automatic measuring system is highly dependent on the accuracy of pressure transmitter. A minimum measurable height is inevitable for each measuring system. When the oil level in tank is lower than this minimum, a measuring error larger than predetermined value may be caused.
