Embodiment Construction
[0051] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0052] A method for making a density distribution table of an oil storage tank, which comprises a basic data acquisition instrument, an oil storage tank oil product density distribution model, and a calculation method.
[0053] There are three basic data acquisition instruments: the first one is a liquid level instrument, which is used to measure and transmit the real-time height H of the oil in the tank; the second one is a temperature instrument, which is used to measure and transmit the real-time height H of the oil in the tank. Temperature K; the third, the pressure gauge, is used to measure and transmit the instant pressure P of the oil in the tank. The three parameters H, P, and K are all functions of a certain time t.
[0054] The oil density distribution model of the oil storage tank, such as figure 1 Shown:
[0055] Taking the vertical vault...

The invention discloses a tabulation metering method of oil product density of an oil storage tank. The method comprises the following steps: abstracting a distribution condition of oil product density in the oil storage tank into an oil product density distribution model of the oil storage tank; obtaining basic data of pressure, temperature and oil height of each point of the oil product inside the tank by an instrument; calculating the density of corresponding point according to incremental punctate distribution in a fusion zone; and finally providing an oil storage tank density distribution table of taking the oil height as a function. By adopting the tabulation metering method, the oil product density distribution condition of the oil storage tank is really reflected in a manner of 'the oil storage tank density distribution table'; necessary conditions are provided for change of average density measurement for the oil product of the oil storage tank and improvement of the metering accuracy of the oil product of the oil storage tank; the accuracy is improved as to an oil payment operation of an oil depot, especially automatic 'instant density' oil payment; the efficiency is improved; the necessary conditions are provided for reduction of the labor intensity; the metering accuracy is improved as to metering of the quality and inventory balances of a new oil product of the oil storage tank; a condition is created for control of profit and loss.
Description
technical field [0001] The present invention relates to a method for tabulating and measuring the density of oil products in oil storage tanks, in particular to a method that is different from the traditional method of manually collecting the average density of oil products in oil storage tanks, using automated information tools as the production and transmission means, and can provide A method for making a 'storage tank density distribution table' with the oil product height of the oil storage tank as a function. Background technique [0002] For a long time, enterprises such as oil depots and refineries have used manual measurement of the "average density" of oil products in storage tanks as the paid oil density in the sales and outbound (factory) business activities of oil products. Generally, each morning and afternoon each day Collect once and enter it into the oil delivery instrument system (or read it manually) to carry out oil quality delivery. Due to the difference...
