摘要： A method for inventory maintenance and leak detection in liquid storage tanks and dispensing lines, that combines tank level measurements, tank product temperature measurements, output flow measurements, liquid product characteristics data, initial product delivery volume data, and redundantly calculates changes in the quantity of liquid product within the tank and compares these calculations to determine abnormalities in the changes in the quantities of product within the tank. Changes in the quantity of product within the tank are verified as either the delivery of additional product into the tank or the dispensing of product from the tank as with a customer sale. Changes that cannot be verified as either delivery into or dispensing from the tank are appropriately characterized as possible leak conditions in the tank or lines. The system additionally incorporates an accuracy improving process of restrapping or recharacterizing the physical conditions within the tank and recalibrating the flow meters associated with dispensing product from the tank. The combination of redundant measurements of volume changes and continuous recalibration of system measurements, along with the incorporation of product temperature measurements and product liquid/vapor state determinations, allows the system to detect with greater accuracy anomalies in the quantity of product within the tank.
摘要翻译：液体储存罐和分配管线中库存维护和泄漏检测的方法，其结合了罐体液位测量，罐产品温度测量，输出流量测量，液体产品特性数据，初始产品输送量数据，并冗余地计算在罐内的液体产品，并比较这些计算，以确定罐内产品数量变化的异常。罐中产品数量的变化将被验证为向客户交付附加产品或者与客户销售一起从罐中分配产品。不能被验证为从罐中输送或分配的变化被适当地表征为罐或管线中的可能的泄漏状况。该系统还包括精确改进过程，以重新调节或重新定位罐内的物理条件，并重新校准与罐分配产品相关联的流量计。体积变化的冗余测量和系统测量的连续重新校准的组合以及产品温度测量和产品液体/蒸汽状态测定的结合允许系统以更精确的方式检测罐内产品的数量异常。
