一、计量纠纷产生的原因分析1.计量器具准确度引起的偏差计量器具准确度偏差有两层含义:一是两种计量器具的准确度不一致;二是计量器具本身的准确度与允许范围出现偏差。贸易交接通常都有国际通行的允许误差范围,原油的允许误差为±0.5%,成品油的允许误差为±0.3%,交接双方也可以约定一个双方都能认可的允许误差范围。当两种计量器具的合成不确定度超过贸易交接的允许误差范围时,就会导致计量纠纷。例如,海南炼化的成品油出厂采用质量流量计作为交接计量器具,对方使用船舶计量进行比对,质量流量计计量的
First, the analysis of the causes of measurement disputes 1. Measuring instruments caused by the accuracy of deviation Accuracy of measuring instruments have two meanings deviation: First, the accuracy of the two measuring instruments inconsistent; Second, the accuracy of the measuring apparatus itself and the allowable range deviation. Custody transfer usually has an internationally accepted tolerance range of ± 0.5% for crude oil and ± 0.3% for refined oil, and both parties may agree on a permissible tolerance range that is acceptable to both parties. When the combined uncertainty of the two measuring instruments exceeds the allowable error range of the custody transfer, it will lead to measurement disputes. For example, Hainan refinery refined oil products shipped at the factory as the delivery of measuring instruments, the other side using the ship to compare the measurement, the mass flow meter measurement
