Dear All;

Good day. I have a flow meter range 5-70 Cm/hr and out is 4 to 20 mA.

first i want to ask how i calculate that at 13 mA what is flow reading?

Second for GE PLC 90-30 cani use the 0 to 32000 counts for that range?

Regards

Hello,

Linear scaling is:

output = ((input value - input low) / (input high - input low)) * (output high - output low) + output low

You can use any range the system provides.
