The thinking method of specifying parameter is as follows: K1 & K2 will be specified as input actual flow span ratio in output actual flow span. In the above case, the actual flow span is specified [Max flow Minimum flow]. We consider K1 and K2 as ratio in the output span and calculate them into the equation. In the case of M2ADS, the equation is as below:
When you use the output actual value span 10 m3/h as the base, each input ratio should be specified as follows:
That is K1 = 0.25 and K2 = 0.75 For example, if Input 1 is 12 mAdc then the input ratio is 0.5 and if Input 2 is 20 mAdc then the input ratio is 1.0, it means that Input 1 ratio is calculated as (12 4) / (20 4) and Input 2 ratio is calculated as (20 4) / (20 4) In this case, the output will be calculated as below and the output ratio will be 0.875.
To convert 0.875 to output current value, then you can find it as 18 mAdc.
