About

FlowAnalyzer

Features
Read full description

FlowAnalyzer brings professional hydraulic analysis to your mobile device. Analyze and visualize water distribution networks with simulation powered by the industry-standard EPANET 2.3.5 engine. Results are shown in the units declared in your .inp file. PROFESSIONAL ANALYSIS Run comprehensive hydraulic simulations to analyze pressure, head, flow, and velocity throughout your network. Color-coded results show where pressure is low or velocity is high against fixed reference bands. They are a visual aid, not design criteria: verify against the locally applicable standard. VISUALIZATION View your network with color-coded nodes and pipes that show hydraulic conditions. A legend shows the pressure and velocity color bands in your network's units and marks nodes with no flow path. Zoom up to 2000x to inspect individual components in detail. KEY FEATURES • Import and analyze EPANET .inp files • Run steady-state and extended period simulations • Interactive network visualization with color coding • View pressure, head, demand, flow, and velocity results • Detailed node and pipe properties • Component counts by type (junctions, tanks, reservoirs, pipes, pumps, valves) • Engine warnings shown after each run • Sample networks included for learning • Optional Google Maps background under your network (uses Google Maps and needs a connection) • Field notes that can save your GPS position (kept on your device) FREE VERSION: • Networks of any size • Run hydraulic simulations • View pressure maps over time • Create and edit patterns FLOWANALYZER PRO (one-time in-app purchase): • Export results to PDF reports • Export data to CSV • Export your network as an .inp file • Save your network's alignment on the map One-time purchase. No subscription. DESIGNED FOR PROFESSIONALS Built for water engineers, hydraulic consultants, urban planners, and water utility professionals. From a small neighborhood network to a city-wide system, FlowAnalyzer sets no limit on network size; simulation time on very large models depends on your device. FIELD-READY Analyze networks on-site, in the field, or in the office. The network, the calculation and your files work without internet. The optional map background needs a connection. Open .inp files from your device storage, cloud drives available in the system file picker, or email attachments. TECHNICAL CAPABILITIES • Supports junctions, tanks, and reservoirs • Handles pipes, pumps, and valves • Warnings when a run is halted as hydraulically unbalanced • Extended period simulation (EPS) • Time-based analysis with interactive timeline EDUCATIONAL TOOL Useful for students and professors teaching hydraulic engineering, water resources, or civil engineering courses. Use included sample networks to learn hydraulic principles and network behavior. ABOUT THE ENGINE Uses EPANET 2.3.5, the open-source release of the hydraulic modeling engine originally developed by the U.S. Environmental Protection Agency (EPA). FlowAnalyzer is an independent application developed by Transparent Blue Water LLC and is not affiliated with, endorsed by, or sponsored by the EPA. EPANET is a trademark of the EPA. Results depend on your model and its data. Verify them independently before using them for design or operation decisions. FlowAnalyzer does not certify compliance with any design standard. GET STARTED Import your existing .inp files. Run a simulation with a single tap and see the results on your network. Download FlowAnalyzer today and bring professional hydraulic analysis to your mobile device.

Verdict

The call

The clearest difference is in-app purchases: Engineering Converter at none against FlowAnalyzer's 1. FlowAnalyzer's advantage is ads (none vs shown) and update cadence (every 2 weeks vs every 42 months). On price, device support and iOS requirement there is nothing between them.
