1080 +== 6.4 How to measure the depth of other liquids other than water? ==
1081 +
1082 +
1083 +Test the current values at the depth of different liquids and convert them to a linear scale.
1084 +Replace its ratio with the ratio of water to current in the decoder.
1085 +
1086 +**Example:**
1087 +
1088 +Measure the corresponding current of the sensor when the liquid depth is 2.04m and 0.51m.
1089 +
1090 +**Calculate scale factor：**
1091 +Use these two data to calculate the current and depth scaling factors：(7.888-5.035)/(2.04-0.51)=1.86470588235294
1092 +
1093 +**Calculation formula：**
1094 +
1095 +Use the calibration formula：(Current current - Minimum calibration current)/Scale factor + Minimum actual calibration height
1096 +
1097 +**Actual calculations：**
1098 +
1099 +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
