Tuning a Water Flow (PI) Loop: A Step-by-Step Guide for Site Engineers

Is your water flow control loop oscillating, jittery, or slow to settle? In this webinar, we walk site and process control engineers through a practical, field-tested method for tuning a PI water flow controller — from inspecting the hardware through to calculating and testing new settings. Water flow loops sit behind density control, level control, heat exchange, and wash water addition across a processing facility. When they're poorly tuned, the result is poor grind or separation, unnecessary equipment wear, and lost grade or recovery. This session shows you how to fix that. What you'll learn: How to run a field inspection before touching any controller settings How to read a SCADA/historian trend to diagnose oscillation and noise issues How to calculate new PI settings using the Lambda (λ) tuning method, with a full worked example The difference between independent and dependent PID controller structures (and why it matters before you type in a new gain) How to test and iterate on new settings using load response vs setpoint response Practical extras: filter block (LAG) considerations and checking valve actuator deadband/resolution in the field
