Fits compact variable-area liquid flow indication where you need a GF Signet / Georg Fischer 807 Series Type 123 short-tube rotameter covering about 2.5–1,000 l/h on d16–d32 lines at PN10.
Key advantages
- Principle — Variable-area short-tube Type 123 / SK
- Scale — About 2.5 to 1,000 l/h (SK50–SK73 family)
- Pipe sizes — d16/DN10 to d32/DN25 (⅜–1 in)
- Pressure — PN10
- Materials — PVC-U or PSU tube; PVDF/PTFE float options; EPDM gaskets
Typical applications
- Skid liquid flow indication.
- Compact plastic piping rotameters.
- Visual flow confirmation on DN10–DN25.
Selection guide
- Tube material — PVC-U vs PSU
- Float / media — Chemical compatibility
- Scale — l/h band needed
- End connections — Pipe OD / DN
Common mistakes
- Exceeding PN10.
- Media attack on PVC-U/PSU/EPDM.
- Expecting magmeter accuracy class.
When to RFQ / what to tell us
- Tube/float materials, scale, connections.
- Quantity and ship-to.
