Taxonomy & Theory > Complete Flow Taxonomy
MADE complete Flow Taxonomy: Signal
This is the complete, verbatim Signal flow taxonomy shipped inside the MADE 3.9.1 desktop application's internal data file (not from any web source). Every flow type MADE offers under the Signal category is listed with its measurable flow properties and the units MADE accepts for each (SI and Imperial). See low-taxonomy-failure-mode-model.md for how the Very High/High/Nominal/Low/Very Low failure-mode bands shown implicitly here are defined quantitatively (they are standardized across nearly every property in this file).
Continuous
