Xiaoling 76.2 1093 Test the current values at the depth of different liquids and convert them to a linear scale.
1094 Replace its ratio with the ratio of water to current in the decoder.
Bei Jinggeng 76.1 1095
Bei Jinggeng 78.1 1096 **Example:**
Bei Jinggeng 76.1 1097
Bei Jinggeng 78.1 1098 Measure the corresponding current of the sensor when the liquid depth is 2.04m and 0.51m.
1099
1100 **Calculate scale factor:**
1101 Use these two data to calculate the current and depth scaling factors:(7.888-5.035)/(2.04-0.51)=1.86470588235294
1102
1103 **Calculation formula:**
1104
1105 Use the calibration formula:(Current current - Minimum calibration current)/Scale factor + Minimum actual calibration height
1106
1107 **Actual calculations:**
1108
1109 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
