I used a clamp-on ultrasonic flow meter on our 4" main at 5 a.m. last Tuesday during a nozzle package change and found two greens loops running 12–15% high versus spec; after recalculating station flows and trimming run times, nightly demand dropped about 18,000 gallons. Anyone favor temporary mag meters or trust controller-calculated flow for seasonal audits when the goal is tighter scheduling and early leak detection?
