Hello, First you have to scale the analog input, can be done with analog amplifier, see: Scaling Question Then you set the parameterset of the PI to user defined, play with the values (start with Short TI) to get a good result. Just start with one flowmeter and one valve to see how it works. Regards, Marcjan |
