The SHO-FLOW app is a dual featured application that can be used with or without a TFT SHO-FLOW® Bluetooth® flow meter. When used in conjunction with a SHO-FLOW, users can determine actual flow rates for fire hose lines and nozzles as well as calculate true Pump Discharge Pressures (PDP), Nozzle Reaction, and Hose Friction. In addition an NFPA 1962 nozzle flow test can be performed. As a stand-alone water flow calculator, many of these functions can be performed using established fire flow formulas. The app also includes water flow education videos and recommendations for target fire flows when using water or foam. The TFT SHO-FLOW flow meter is designed to quickly determine flow rates present in a fire hose line and wirelessly transmit the rate to a nearby smart device. Any firefighting, training, or testing operation that utilizes hose lines or nozzles is a potential application. Please read the manual before operation.
