177
The accuracy is specified in relation to the mass flow.
±1.0% ±(current measured value in % -100%) × 0.07 for 100% to 200% of the calibrated
measuring range (under reference operating conditions)
Accuracy of outputs
The outputs have the following base accuracy specifications.
Current output
Accuracy
±5 µA
Pulse/frequency output
o.r. = of reading
Accuracy
Max. ±50 ppm o.r. (over the entire ambient temperature range)
Repeatability
±0.25 % of the display value for velocities above 1.0 m/s (3.3 ft/s)
Response time
Typically < 3 s for 63 % of a step change (in both directions)
Influence of ambient
temperature
Current output
Temperature coefficient
Max. 1 μA/°C
Pulse/frequency output
Temperature coefficient
No additional effect. Included in accuracy.
Influence of medium
temperature
Air: 0.02 % per °C (0.036 % per °F) of the process temperature change in relation to the
reference temperature
Influence of medium
pressure
Air: 0.3 % per bar (0.02 % per psi) of the process pressure change (from the set process
pressure)
