Performance specifications

The following performance specifications are for all Rosemount models except where
noted. Digital performance specifications applicable to Digital HART output.
Flow accuracy
Includes linearity, hysteresis, and repeatability.
Liquids—for Reynolds Numbers over 20000
Digital and Pulse Output
±0.65% of rate
Note
The accuracy for the 8800DR, line sizes 6 to 12 inch (150 to 300mm), is ±1.0% of rate.
Analog output
Same as pulse output plus an additional 0.025% of span
Gas and steam— for Reynolds Numbers over 15,000
Digital and Pulse Output
±1.0% of rate
Note
The accuracy for the 8800DR, line sizes 6 to 12 inch (150 to 300mm), is ±1.35% of rate.
Analog Output
Same as pulse output plus an additional 0.025% of span.
Accuracy limitations for gas and steam:


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%.
Process temperature accuracy
2.2 °F (1.2 °C) or 0.4% of reading (in °C), whichever is greater.
Note
For remote mount installations, add ±0.018 °F/ft. (±0.03 °C/m) of uncertainty to the
temperature measurement.
