The cylindrical tank has been fitted with two distance sensors, which are of infrared form, before shipment.
Because the shapes are different in fig. 5, 6 and 7, the change degree according to each index is different, different formulas are adopted for different types, and different experimental data are also adopted, so that the detection result is more practical, and the positions of dividing lines are the same due to the different sizes of a and b, therefore
Before leaving factory, the cylindrical oil tank is not filled with oil, and the two distance sensors detect the distance between the inner walls of the cylindrical oil tank to obtain D 1 D (D) 2 As shown in fig. 8 and 9,since the end face of the distance sensor may protrude or retract into the inner wall of the cylindrical tank, and the detection should be the distance from the inner wall of the cylindrical tank to the liquid surface, it is necessary to adjust the output of the distance sensor. Assume that a distance sensor outputs X 1 Another distance sensor outputs X 2 Then L 2 ＝X 1 -(D 1 -D)，L 3 ＝X 2 -(D 2 And D), the detection distances L2 and L3 of the two distance sensors are corrected, so that the detection result is more accurate, and the influence on the measurement result caused by inaccurate installation positions of the distance sensors is avoided.

s85, selecting 9 cylindrical glass bottles with different inner diameters and different heights, wherein one end of each glass bottle is connected with an opening and closing cover in a threaded manner;
s86, placing the plasticine on a horizontal plane;
s87, filling colored water into glass bottles by using a measuring cup, measuring the real water quantity of the colored water in each glass bottle by using the measuring cup, ensuring that three corners of the bottom of each glass bottle are covered by the colored water, and then carrying out the following steps on each glass bottle: s871, pressing a glass bottle filled with colored water on the plasticine, and ensuring that only three corners of the pressed glass bottle are covered by the colored water; s872, recording D, H, M, L1 and real water volume V of each glass bottle by using positions of two distance sensors at the notes on the outer wall of the glass bottle by using a color pen True sense The method comprises the steps of carrying out a first treatment on the surface of the S873, measuring the vertical distance from the positions of the two distance sensors to the liquid level by using a ruler to obtain L2 and L3; s874, adjusting the horizontal angle a of the glass bottle, ensuring that the plasticine stably supports the bottom of the glass bottle, and then repeating the step S873; s875, repeatedly executing the step S874 for 5 times, and measuring each glass bottle for 6 times to obtain 9*6 times of test data;
s88, substituting 54 experimental data into the formula 3, and calculating to obtain a constant h by a quadratic fitting mode 0 ,h 1 ,h 2 ,n 1 ,n 2 ,p 1 ,p 2 ,q 1 ,q 2 。
