How it works

From diagram to report in three steps

Build the network

Place nodes and connect them with lines on the canvas. Optionally trace a floor plan or site layout as a background reference.

Calculate

One click — an automatic hydraulic calculation balances flow rates and pressures across the whole network using the independent-loop method.

Get the report

Export tabular results to Excel or PDF, or print the network diagram with an editable legend.
