Go Beyond EPANET.Without the Enterprise Price.
Import your EPANET model and run pressure-driven analysis, 24-h extended-period simulation, and operational diagnostics — criticality, leak estimation, valve isolation — right in your browser.

Two Platforms, One Mission
Whether you manage a small network or a complex distribution system, FlowAnalyzer scales with you.
Web for the office. Mobile for the field.
From Your EPANET Model to a Decision
Import, simulate, diagnose, and report — all in your browser.
Import
Load your EPANET .inp — or start from an example
Simulate
Pressure-driven analysis, 24-h EPS, and pressure profiles
Diagnose
Criticality, leak estimation, and valve-isolation impact

Export technical PDF and CSV results
Operational Diagnostics EPANET Can't Do
See which pipes are most critical, estimate where you're losing water, and know exactly who loses service when a main breaks — pressure-driven, in your browser.
- Critical Components: rank the pipes that hurt most if they fail (N-1)
- Valve Isolation: which valves to close, who loses water, and the work order in PDF
- Leaks & Efficiency: night-flow leakage (MNF), pressure savings and energy
- Pressure & Service: find the under-served nodes under real pressure
Complete Feature Set
Everything you need to manage your water network efficiently.
FlowAnalyzer Web
Browser-based platform
Pressure profiles
Click a pipe and the profile extends on its own along the main, stopping at every branch so you choose where it goes. Ground elevation, hydraulic grade line and pressure on a single chart, at any hour of the 24-hour run — and out to CSV or PNG.
Take the network to the field
FlowAnalyzer Mobile is the companion app. Open the same EPANET model on site, run the simulation and read pressures, flows and velocities right where the pipe is — with no signal needed.
- Import and view EPANET models (.inp), fully offline
- Complete simulation with color maps for pressure, flow and velocity
- Query any element on site: diameter, material, pressure, flow, zone
- Field Mode with photos, notes and inspection PDF reports
The full toolset lives in the browser. Mobile is for the field.
The whole toolset, free
Every module in FlowAnalyzer Web is open right now — no license, no node limit, no credit card. If it earns its place in your work, you can help keep it that way.
FlowAnalyzer Web
The complete platform, in your browser. Your model never leaves your machine.
- Import your EPANET .inp — or load the example model
- Rust/WASM engine: steady-state and 24-h EPS, DDA or PDA
- EPANET side by side, for verification
- Critical Components, Pressure & Service, Leaks & Efficiency, Valve Stability, Disconnected, Downstream trace
- Pressure profile along a path, and Valve Isolation with Export Work Order (PDF)
- District Metered Areas, DMA audit, Network Validation, Georeferencing
- Network Calibration (beta), Field Signals (beta), Pump Management
- Results table and CSV export — networks of any size, no node limit
Support FlowAnalyzer
FlowAnalyzer is built by a small team and given away because water utilities need the tools more than we need the toll booth. If it saved you a day of work, you can help pay for the next one.
- Your support pays for engine work, servers and hours
- It unlocks nothing — every module stays open for everyone
- Tell us what you need next and it goes to the top of the list
- Utilities, universities and consultancies: write to us about a joint pilot
