#240 – Pitot Gauges: How Do I Calculate the PSI to GPM …
Aug 1, 2019 · In theory, pitot gauges make it simple to measure the flow of fire hydrants and convert readings in pounds per square inch (PSI) to gallons per minute (GPM), enabling inspectors to quickly uncover reduced flow rates.
#46 – How to Use a Pitot Gauge for Hydrant Flow Testing - QRFS
May 20, 2016 · Pitot gauges make it simple to quickly measure the pressure of flowing water from fire hydrants, followed by converting those readings in pounds per square inch (PSI) to gallons per minute (GPM).
