The Isco FlowCalc app calculates flow rates in open, non-full channels and pipes. Use this app to spot-check the performance of installed flow monitoring systems, or verify that newly installed flow meters are configured correctly. This app includes level-to-flow rate calculations for primary devices and area-velocity flow rate calculations for a variety of conduit shapes.
Isco FlowCalc is now available on the App Store.
