DETAILED DESCRIPTION OF THE INVENTION Currently in Japan, land oil (1'+
Floating roof oil tanks are widely used in Japan.Why is this floating roof oil tank used as a storage tank for volatile oil? Floating roof force that moves up and down as the output increases and decreases;? The floating roof is placed in the tank and the oil surface is shielded by a floating roof, eliminating the empty space where volatile gases can exist between the roof and the oil surface, thereby suppressing the generation of flammable gas.
1! In addition to minimizing the consumption of oil in the tank to reduce economic losses, it also suppresses the release of flammable gas to the outside of the tank to prevent disasters and make a significant contribution to pollution control. It is something to do.

However, the structure of this floating roof type oil tank is a cylindrical tank with an open upper part and a nearly perfect circle. A work place is provided, and a hollow pipe that penetrates the floating roof housed in the tank and opens at the bottom of the tank is vertically fixed in the work place, and several oil pipes are placed below the lowermost part of the floating roof. The hollow tube is constructed into a blind tube without making any oil holes beyond that point, and this hollow tube is used as a support for the floating roof, and the floating roof is moved up and down along the support. In the conventional oil depth measurement method, this hollow tube is used as a gauge pole, a tape measure with a weight for sounding is inserted into this hollow tube, and the weight is lowered below the oil surface. When measuring the depth of the oil level by lowering the weight until it reaches the base plate at the bottom of the tank, or by lowering the weight slightly below the oil level and measuring the value between the oil level and a fixed point on the gauge ball, use the value. In some cases, the oil depth is determined by using the value obtained by subtracting the subsidence value as a scale, and a capacity light dedicated to the oil + 1"+ is created in each oil tank, and the capacity corresponding to the oil depth is determined by the capacity light. Therefore, soundings are always taken twice before and after receiving and discharging oil, and the soundings are taken before receiving and receiving oil.
The depth measurement after loading and unloading is called the rear scale, and the fluctuation in the amount of oil in the oil tank is calculated from the difference in oil depth between this fnJ scale and the rear scale. However, to calculate this amount of oil, the oil depth value in ml is determined, the specific gravity of the oil and the oil temperature in the oil tank are measured according to standards, and the results are determined according to JIS-2249-19.
80 (Specific Gravity, Weight, and Volume Conversion Table for Crude Oil and Petroleum Products, Published by the Japanese Standards Association) and the Oil Tank Capacity Light (This capacity light is determined by a professional appraiser who actually measures the oil tank in detail and determines the minimum depth and price tag, and the capacity is in liters. The delivery quantity is determined by the difference in capacity determined by the AfJ scale (however, the standard trading temperature for oil is 15°C). However, this oil tank capacitance light is normally created with the top surface of the substrate on the bottom of the tank located directly below the gauge pole as the lower base point (0), and in this measurement method, the upper Dm aperture of the gauge ball, J: I ) There are cases where the oil depth (2) is determined directly by lowering a tape measure with a weight, and there are cases where the oil depth is determined by measuring the scale above the oil surface.

That is, in the conventional oil depth measuring method, a hollow tube is established vertically from the top of the oil tank to the bottom of the oil tank, and is fixed to the oil tank side plate.The vertical hollow tube is used as a gauge ball, and this vertical hollow The tube acts as a support for the floating roof, and the floating roof uses this hollow tube as a support to move up and down.

Furthermore, the gauge balls used for this sounding form several oil holes only in the areas below the lowest point of the floating roof, and the floating roof rises.On the other hand, no oil holes are formed in the areas where the floating roof rises. The purpose of this is to prevent volatile gas from leaking from the circumferential surface of the gauge pole and to discharge flammable gas to the outside of the tank to prevent disasters. However, there is a height difference between the oil level in the gauge ball and the oil level in the oil tank due to the difference in specific gravity, making it impossible to determine the true oil depth.

In other words, when measuring the oil depth inside this gauge ball, the oil in the gauge ball enters and exits only through the lower end opening and several oil holes, and only moves up and down within the gauge ball that exists above the oil hole. However, if there is a difference between the specific gravity of the oil in the gauge ball and the specific gravity of the oil in the oil tank, a difference (d) will occur in the front of the two, and ? 11] Specific gravity of oil in the tank> When the specific gravity of the oil in the gauge ball is, the oil level in the gauge ball is higher than the oil level in the oil tank by (f), and the specific gravity in the oil tank is higher than the specific gravity in the gauge ball. In the case of , the opposite is true, which causes measurement errors and makes it impossible to accurately calculate the amount of oil.

Also, if the storage oil tank is for crude oil, a large amount of oil sludge will accumulate at the bottom of the tank, blocking the bottom opening of the gauge ball and the oil passage hole.
There will be a huge difference between the oil level in the gauge borer and the oil level in W1 (W1), and the difference may be as much as 1 meter. It is impossible to set the amount of oil at a constant value.

Furthermore, as shown in Figure 4 of the attached drawings, the external shape is a fixed-roof land oil tank with a floating roof inside, and this type of floating-roof oil tank is mainly used to store products such as gasoline and jet oil. The material that makes up the internal floating roof is aluminum or steel, but in this type of oil, the upper fixed roof, side plates, and gauge balls form a mutual relationship to perform sounding work, so workers go around and climb the stairs. When the oil tank reaches the fixed roof, slight vibrations occur in the oil tank body, and the vibrations propagate to the gauge ball, causing the oil level in the sounding tube to oscillate, resulting in the disadvantage that it takes time to check the oil level. In addition, when using a sounding tape measure with a weight submerged in a narrow oil level in a gauge ball, not only does the oil level move up and down, making it impossible to obtain accurate sounding values, but also due to the difference in specific gravity mentioned above. Errors are added and the sounding is repeated, and there are many drawbacks to using gauge balls to determine the oil depth. There is a general need for an improved measurement method that is easy to implement and can yield accurate sounding results, and the present invention is intended to meet these demands.
