78.1	885	Example:
76.1	886
78.1	887	Measure the corresponding current of the sensor when the liquid depth is 2.04m and 0.51m.
	888
	889	Calculate scale factor：
	890	Use these two data to calculate the current and depth scaling factors：(7.888-5.035)/(2.04-0.51)=1.86470588235294
	891
	892	Calculation formula：
	893
	894	Use the calibration formula：(Current current - Minimum calibration current)/Scale factor + Minimum actual calibration height
	895
	896	Actual calculations：
	897
	898	Use this formula to calculate the value corresponding to the current at a depth of 1.5 meters: (6.918-5.035)/1.86470588235294+0.51=1.519810726
