| Operation and Performance |
| Fluid Types |
Saturated or superheated steam |
| Pipe Sizes |
2 in to 48 in (50 mm to 1200 mm) nominal bore (NB) |
| Pipe Materials |
All metals. Consult RS Hydro for other materials |
| Flow Accuracy (velocity) |
±1% to 2% of reading typical
Accuracy depends on pipe size and whether measurement is one-path or two-path. Accuracy to ±0.5% of reading may be achievable with process calibration. |
| Repeatability |
±0.2% to 0.5% of reading |
| Range (Bidirectional) |
1500:1
Specifications assume a fully developed flow profile (typically 20 diameters upstream and 10 diameters downstream of straight pipe run) and flow velocity greater than 3 ft/s (1 m/s). |
| Measrement Parameters |
Mass flow, standard and actual flow, totalized flow, and flow velocity. |
