Reference data
The catalogue, sizing tables, option menus, fluids and corrosion data every recommendation rests on.
The product and process knowledge every recommendation rests on. In FlowOS it is versioned in Postgres — not restored over hand-edits at every restart.
The shape of what Flowtech sells is explained in:
- Item Group Master — the family and the variant axis
- Item Master — a released size/code
- Decodification — the menus that compose the model number
- Product limitations — survive versus read
What else it holds
| Reference set | What it is |
|---|---|
| Fluid library | Fluids and gases with density, phase, viscosity, conductivity, boiling and freezing points, and the names customers actually write |
| Chemical resistance | Per-fluid, per-material published bands (A–D) |
| Measured corrosion rates | Laboratory observations per fluid, alloy, concentration and temperature |
| Saturated steam table | Steam density against pressure — never “steam as water” |
| HSN | Statutory code and split GST rates, as the ERP holds them. Required on finished item codes |
| T&C | Reusable payment, delivery and warranty text selected per quotation |
What the business gets
Naming a fluid brings its properties, so an enquiry that says only “caustic soda” still scores. Trade names and process-stream terms are recognised.
A measured corrosion rate may condemn a material the chart cleared; it may not clear one the chart calls severe, because thinning is blind to pitting (R31). A severe band excludes only when the fluid is not mild overall (R30) — water rates carbon steel badly on the chart and is still Flowtech’s standard build for its most common application.
Coverage is uneven. Where neither a band nor a rate exists, the option is unconfirmed, not hidden (R23). Some entries are deliberately absent (steam as a fluid row, milk of lime) rather than approximated — see Limitations.
Who maintains it
Catalogue maintainers, not the quotation screen. A new datasheet, a revised limitations guide, or a product-list change publishes a new decodification version and, where needed, new item codes. Sent quotations keep the version they pinned.
