	842	+== 6.4 How to measure the depth of other liquids other than water? ==
	843	+
	844	+
	845	+Test the current values at the depth of different liquids and convert them to a linear scale.
	846	+Replace its ratio with the ratio of water to current in the decoder.
	847	+
	848	+**Example:**
	849	+
	850	+Measure the corresponding current of the sensor when the liquid depth is 2.04m and 0.51m.
	851	+
	852	+**Calculate scale factor：**
	853	+Use these two data to calculate the current and depth scaling factors：(7.888-5.035)/(2.04-0.51)=1.86470588235294
	854	+
	855	+**Calculation formula：**
	856	+
	857	+Use the calibration formula：(Current current - Minimum calibration current)/Scale factor + Minimum actual calibration height
	858	+
	859	+**Actual calculations：**
	860	+
	861	+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
