881 +== 6.4 How to measure the depth of other liquids other than water? ==
882 +
883 +
884 +Test the current values at the depth of different liquids and convert them to a linear scale.
885 +Replace its ratio with the ratio of water to current in the decoder.
886 +
887 +**Example:**
888 +
889 +Measure the corresponding current of the sensor when the liquid depth is 2.04m and 0.51m.
890 +
891 +**Calculate scale factor：**
892 +Use these two data to calculate the current and depth scaling factors：(7.888-5.035)/(2.04-0.51)=1.86470588235294
893 +
894 +**Calculation formula：**
895 +
896 +Use the calibration formula：(Current current - Minimum calibration current)/Scale factor + Minimum actual calibration height
897 +
898 +**Actual calculations：**
899 +
900 +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
