In order to accurately calculate dynamic oil quantity of crude oil tanks, a new computation scheme for dynamic oil quantity is developed based on the multi-sensor information fusion, and the mathematic models for calculating oil quantity on-line were established. The calculating dynamic oil quantity in real time can be realized using the data fusion algorithm in measurement system based on multi-sensor. The results via practical applications indicate that the measurement scheme and the computational model can achieve high precision and reliability, and satisfy the requirement of production process. The method may well be applied to calculating dynamic oil quantity of crude oil tanks in united station and the oil-stored tanks in oilfield, and adopted in automatic inventory systems in oil production fields.
