Rosemount 8800D
PERFORMANCE
SPECIFICATIONS
The following performance specifications are for all Rosemount models
except where noted. Digital performance specifications applicable to both
Digital HART and F
OUNDATION fieldbus output.
Flow Accuracy
Includes linearity, hysteresis, and repeatability.
Liquids—for Reynolds Numbers over 20000
Gas and Steam— for Reynolds Numbers over 15,000
NOTE
As the meter Reynolds Numbers decreases below the stated limit to 10,000 the
accuracy error band will increase linearly to +/-2.0%. For Reynolds Numbers down to
5,000 the accuracy error band will increase linearly from +/-2.0% to +/-6.0%.
