PERFORMANCE
SPECIFICATIONS
(System specifications are given using the frequency output and with the unit
at reference conditions.)
Accuracy
Includes the combined effects of linearity, hysteresis, repeatability, and
calibration uncertainty.
Rosemount E Series with 8705/8707 Sensor:
Standard system accuracy is ±0.25% of rate ±1.0 mm/sec from 0.04 to 6
ft./s (0.01 to 2 m/s); above 6 ft./s (2 m/s), the system has an accuracy of
±0.25% of rate ±1.5 mm/sec.
Optional high accuracy is ±0.15% of rate ±1.0 mm/sec from 0.04 to 13 ft./s
(0.01 to 4 m/s); above 13 ft./s (4 m/s), the system has an accuracy of
±0.18% of rate.

Rosemount E-Series with 8711 Sensor:
Standard system accuracy is ±0.25% of rate ±2.0 mm/sec from 0.04 to 39
ft./s (0.01 to 12 m/s).
Optional high accuracy is ±0.15% of rate ±1.0 mm/sec from 0.04 to 13 ft./s
(0.01 to 4 m/s); above 13 ft./s (4 m/s), the system has an accuracy of
±0.18% of rate.
Rosemount E-Series with 8721 Sensor:
Standard system accuracy is ±0.5% of rate from 1 to 39 ft./s (0.3 to 12
m/s); between 0.04 and 1.0 ft./s (0.01 and 0.3 m/s), the system has an
accuracy of ±0.005 ft./s (0.0015 m/s).
(1) For Sensor sizes greater than 12 in. (300 mm) the high accuracy is ±0.25% of rate from 3 to
39 ft./sec (1 to 12 m/sec).
