WebWater flow monitoring or flow based water leak detection and automatic shut-off systems work by monitoring both the volume and amount of time water is moving through pipes. They use a flow meter and compare water volumes against set thresholds. When abnormal flow is detected, usually due to a burst or faulty pipe, the valve automatically closes ... WebApr 30, 2024 · The two speeds are related as. (5.2.3) v ¯ t = v ¯ s + σ s 2 v ¯ s. The time mean speed higher than the space mean speed, but the differences vary with the amount of variability within the speed of vehices. At high speeds (free flow), differences are minor, whereas in congested times, they might differ a factor 2.
