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 A- 3 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)
Repeatability (small volume) Better than 0.5 %
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 0.0001 m/s (0.003 ft/s)
Flow Profile Compensation Automatic Reynolds number correction of
reported flow rate.
