  1. Thanks Joe for answering if you want to maintain a constant flow, my question is the input pulse would have to bridge for the two entries because one of them is to tote and one for frequency, I also toltal total quantity of liquid in the PID PV would be my entry frequency input such 10Pulsed per second (10Hz), then I would have to maintain a fixed rate to a setpoint travez, please if you could help me with this that still do not understand well, the analog output for the inverter would have to linearize Thanks
  2. 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
