| Operation and performance |
| Fluid types |
Liquids: acoustically conductive fluids, including most clean liquids, and many liquids with small amounts of entrained solids or gas bubbles. |
| Flow measurement |
Correlation transit time model |
| Accuracy |
3 to 24 in (80 to 600 mm)
- ±0.25% of reading for velocities above 1.6 ft/s (0.5 m/s)
- ±1.25 mm/s for velocities below 1.6 ft/s (0.5 m/s)
2 in (50 mm) - ±0.5% of reading for velocities above 1.6 ft/s (0.5 m/s)
- ±2.5 mm/s for velocities below 1.6 ft/s (0.5 m/s)
Accuracy statement assumes measurement of a single phase homogenous liquid with a fully developed symmetrical flow profile passing through the meter (typically 10 diameters upstream and 5 diameters downstream of straight pipe run).
Applications with piping arrangements that create an asymmetrical flow profile may require extended piping straight runs and/or flow conditioning for the meter to perform to this specification. |
| Calibration |
All meters are water calibrated at ambient conditions and include a calibration certificate.
- 3 points as found 2, 5, and 10 ft/s (0.6, 1.5 and 3 m/s) and 2 points as left 3 and 7 ft/s (0.9 and 2.1 m/s)

| Repeatability |
