878 +== 6.4 How to measure the depth of other liquids other than water? ==
879 +
880 +
881 +Test the current values at the depth of different liquids and convert them to a linear scale.
882 +Replace its ratio with the ratio of water to current in the decoder.
883 +
884 +**Example:**
885 +
886 +Measure the corresponding current of the sensor when the liquid depth is 2.04m and 0.51m.
887 +
888 +**Calculate scale factor：**
889 +Use these two data to calculate the current and depth scaling factors：(7.888-5.035)/(2.04-0.51)=1.86470588235294
890 +
891 +**Calculation formula：**
892 +
893 +Use the calibration formula：(Current current - Minimum calibration current)/Scale factor + Minimum actual calibration height
894 +
895 +**Actual calculations：**
896 +
897 +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
