954 +
955 +
956 +Test the current values at the depth of different liquids and convert them to a linear scale.

958 +
959 +**Example:**
960 +
961 +Measure the corresponding current of the sensor when the liquid depth is 2.04m and 0.51m.
962 +
963 +**Calculate scale factor：**
964 +Use these two data to calculate the current and depth scaling factors：(7.888-5.035)/(2.04-0.51)=1.86470588235294

967 +
968 +Use the calibration formula：(Current current - Minimum calibration current)/Scale factor + Minimum actual calibration height
969 +
970 +**Actual calculations：**
971 +
972 +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
