Abstract

The invention provides a measuring device for measuring the composition of oil and water in an oil tank, comprising: a first liquid level detector for detecting the height of the oil-water interface liquid level, and a second liquid level detector for detecting the height of the upper oil liquid level A device, and a controller, wherein the controller subtracts the oil-water interface liquid level measurement signal and the oil liquid level measurement signal obtained by the first and second liquid level detectors, thereby obtaining the oil-water composition in the oil tank.

Description

technical field [0001] The invention relates to a detection device and method for measuring the oil-water interface in a large oil tank. Background technique [0002] Large oil tanks are usually used to store crude oil or other petroleum products in refineries, oil fields, oil depots and other industries, with a capacity of more than 100 cubic meters, consisting of tank walls, tank roofs, tank bottoms and other accessories. [0003] There is also a situation that there are other liquid impurities in the oil tank, usually water. Therefore, it is necessary to measure the respective components of oil and water in the oil tank, so that the actual amount of crude oil products in the oil tank can be obtained more accurately, and water can be mixed into the crude oil products during use. However, in the prior art, there is no effective method for measuring the respective compositions of oil and water. [0004] Due to the flammability and explosiveness of crude oil products, it is...
