Xiaoling 76.2 1091 Test the current values at the depth of different liquids and convert them to a linear scale.
1092 Replace its ratio with the ratio of water to current in the decoder.
Bei Jinggeng 76.1 1093
Bei Jinggeng 78.1 1094 **Example:**
Bei Jinggeng 76.1 1095
Bei Jinggeng 78.1 1096 Measure the corresponding current of the sensor when the liquid depth is 2.04m and 0.51m.
1097
1098 **Calculate scale factor:**
1099 Use these two data to calculate the current and depth scaling factors:(7.888-5.035)/(2.04-0.51)=1.86470588235294
1100
1101 **Calculation formula:**
1102
1103 Use the calibration formula:(Current current - Minimum calibration current)/Scale factor + Minimum actual calibration height
1104
1105 **Actual calculations:**
1106
1107 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
