INFLOW_INFILT_DET
Inflow and infiltration detection by comparing catchment flow against its dry-weather baseline, with I/I volume totalising.
When to use it
Use INFLOW_INFILT_DET when a catchment or sub-catchment has a metered sewer flow and a known dry-weather baseline, and the operator needs to know how much of what is being pumped is groundwater or stormwater rather than sewage.

Create a free Ri Tech account to download the block. You get the Structured Text body, the Rockwell Add-On Instruction (.L5X), the Schneider Control Expert DFB (.XDB), PLCopen XML, the IEC 61499 function block type (.fbt) and the datasheet.
Every block in the catalogue is free to download, in every format, with no purchase and no card. Browsing needs no account at all; downloading needs a signed-in one, so the block lands in your library and re-downloads whenever you need it.
Source is never published on this page. The implementation is released to a signed-in Ri Tech account — free of charge, but never anonymously.
