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
