For a limited time - get this $2.99 app for free. This 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. You can display flow rate units as cubic feet per second (cfs), gallons per minute (gpm), or million gallons per days (mgd). By changing the app settings to SI units, you can display flow rates as liters per second (lps) or cubic meters per hour (m3h). Level-to-Flow Rate Calculations for Primary DevicesEnter the head height using convenient sliders to calculate flow rates in the following primary devices: Parshall flumes from 1 inch to 12 feet (0.0254 to 3.66 m) Palmer-Bowlus flumes from 4 to 30 inches (0.102 to 0.762 m) V-notch weirs: 22.5, 30, 45, 60, 90, 120 degrees Rectangular weirs with end contractions from 1 to 10 feet (0.3 to 3.0 m) Rectangular weirs without end contractions from 1 to 10 feet (0.3 to 3.0 m)Area-velocity Flow Rate CalculationsEnter the head height, velocity, and dimensions to calculate flow rates in these channel shapes: Round pipes to 30 feet (10 m) in diameter U-shaped channels to 30 feet (10 m) wide Rectangular channels to 30 feet (10 m) wide Trapezoidal channels to 30 feet (10 m) wide Elliptical pipes to 30 feet (10 m) wideSave your frequently-used calculations as Favorites. This handy feature lets you quickly access calculations by site name and map your location when GPS data is available. All flow rate calculations are based on equations published in the Isco Open Channel Flow Measurement Handbook, Sixth Edition. This definitive reference book, published by Teledyne Isco, is widely used by water and wastewater monitoring professionals.
