Accuracy
Rosemount 8705 with 8712D, 8732C, or 8742C
±0.5% of rate from 1 to 30 ft/s (0.3 to 10 m/s). Includes combined effects
of linearity, hysteresis, repeatability, and calibration uncertainty. Accuracy
is ±0.005 ft/s (±0.0015 m/s) from low-flow cutoff to 1.0 ft/s (0.3 m/s).
Rosemount 8707 with 8712D/H, 8732C, or 8742C
±0.5% of rate from 3 to 30 ft/s (1 to 10 m/s). Include combined effects of
linearity, hysteresis, repeatability and calibration uncertainty. Accuracy is
±0.015 ft/s (±0.0045 m/s) from low-flow cutoff to 3.0 ft/s (1 m/s).
