1. wind speed and current computing relationship

  For example, the range is 0~30m/s, the analog output is 4~20mA current signal, wind speed and current The calculation relationship is as shown in the formula: C = (A2-A1) * (X-B1) / (B2-B1) + A1, where A2 is wind speed range upper limit, A1 is the lower limit of the range, B2 is current output range upper limit, B1 is the lower limit, X is the currently read wind speed value, and C is the calculated current value. The list of commonly used values is as follows:

current(mA)	wind speedValue (m/s)	Calculation Process
4	0.0	(30-0)*(4-4)÷(20-4)+0
5	1.9	(30-0)*(5-4)÷(20-4)+0
6	3.8	(30-0)*(6-4)÷(20-4)+0
7	5.6	(30-0)*(7-4)÷(20-4)+0
8	7.5	(30-0)*(8-4)÷(20-4)+0
9	9.4	(30-0)*(9-4)÷(20-4)+0
10	11.3	(30-0)*(10-4)÷(20-4)+0
11	13.1	(30-0)*(11-4)÷(20-4)+0
12	15.0	(30-0)*(12-4)÷(20-4)+0
13	16.9	(30-0)*(13-4)÷(20-4)+0
14	18.8	(30-0)*(14-4)÷(20-4)+0
15	20.6	(30-0)*(15-4)÷(20-4)+0
16	22.5	(30-0)*(16-4)÷(20-4)+0
17	24.4	(30-0)*(17-4)÷(20-4)+0
18	26.3	(30-0)*(18-4)÷(20-4)+0
19	28.1	(30-0)*(19-4)÷(20-4)+0
20	30.0	(30-0)*(20-4)÷(20-4)+0

    As shown in the above formula, when measuring 8mA, current current is 11.5m/s。

2. conductivity and current computing relationship

  For example, the range is 0~360°, the analog output is 4~20mA current signal, conductivity and current The calculation relationship is as shown in the formula: C = (A2-A1) * (X-B1) / (B2-B1) + A1, where A2 is conductivity range upper limit, A1 is the lower limit of the range, B2 is current output range upper limit, B1 is the lower limit, X is the currently read conductivity value, and C is the calculated current value. The list of commonly used values is as follows:

current(mA)	conductivityValue (°)	Calculation Process

5	22.5	(360-0)*(5-4)÷(20-4)+0
6	45.0	(360-0)*(6-4)÷(20-4)+0
7	67.5	(360-0)*(7-4)÷(20-4)+0
8	90.0	(360-0)*(8-4)÷(20-4)+0
