Straight run should be at least 20x the piping diameter when an elbow, tee, filter or other disruption exists upstream of the meter. WebIdeally the control valve response should be linear (from the control system’s perspective). If the PID output changes 5%, the process should respond in a similar fashion regardless of where the output is. (In other words 15% to 20% or 85% to 90% should ideally generate the same process response.) If the valve response is non-linear, control ...
