Low-Flow Flow Meter Calibration: Practical Steps for Accuracy

Low-flow calibration is the disciplined process of verifying and adjusting a flow meter’s output when operating at flow rates near the bottom of its measurement range — typically below 10–20% of the meter’s full-scale capacity. In these regions, signal-to-noise ratios collapse, environmental disturbances dominate, and small systematic biases that would be negligible at full scale […]
