78.1	959	Example:
76.1	960
78.1	961	Measure the corresponding current of the sensor when the liquid depth is 2.04m and 0.51m.
	962
	963	Calculate scale factor：
	964	Use these two data to calculate the current and depth scaling factors：(7.888-5.035)/(2.04-0.51)=1.86470588235294
	965
	966	Calculation formula：
	967
	968	Use the calibration formula：(Current current - Minimum calibration current)/Scale factor + Minimum actual calibration height
	969

	972	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
