Performance
The following specifications apply under standard conditions (i.e., measurements taken on a
straight run of 15 diameters upstream and 5 diameters downstream; flow rate above 1 fps;
non-aerated Newtonian liquids flowing at Reynolds numbers <2000 or >10000).
Table 11- 1 Performance Specifications
Transit-Time Accuracy At least ±1% to ±2 % of indicated flow (better
than ±0.5 % possible with calibration.)
Flow Sensitivity
0.0003 m/s (0.001 fps) - even at zero flow.
Zero Drift Stability
Less than 0.005 m/s (0.015 fps)
Batch Repeatability
±0.15 % of flow
Response Rate (Damping) SmartSlew effective from 0.2 seconds to 5
minutes.
Flow Velocity Range
Min. ±12 m/s (±40 ft/s), inc. zero flow
Linearity
0.001 m/s (0.003 ft/s)
Flow Profile Compensation Automatic Reynolds number correction of report-
ed flow rate.
