842		-== 6.4 How to measure the depth of other liquids other than water? ==
843		-
844		-
845		-Test the current values at the depth of different liquids and convert them to a linear scale.
846		-Replace its ratio with the ratio of water to current in the decoder.
847		-
848		-**Example:**
849		-
850		-Measure the corresponding current of the sensor when the liquid depth is 2.04m and 0.51m.
851		-
852		-**Calculate scale factor：**
853		-Use these two data to calculate the current and depth scaling factors：(7.888-5.035)/(2.04-0.51)=1.86470588235294
854		-
855		-**Calculation formula：**
856		-
857		-Use the calibration formula：(Current current - Minimum calibration current)/Scale factor + Minimum actual calibration height
858		-
859		-**Actual calculations：**
860		-
861		-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
