hello
Friends need your help please, I need to keep constant the pressure of a liquid I am using a flowmeter with pulse output of 198.4 ppg, please an idea to use the PID function in high-speed input function would have to use the frequency counter, and then linearized, and an analog output to control a frequency for the pump, please if you could expand to have a clearer idea of the PID function, using a VISION 130.
THANKS FOR YOUR HELP
