K
L • Q = 100 to 150 %:
from ±3 %to ±6.5 % of the
current measured value
increasing linearly as expressed in
the following equation:
±3 ± (X
n
-100) × 0.07[% o.r.]
(100 %< X
n
≤150 %; X
n
= current
flow as a % o.f.s. )
• Q = 15 to 100 %:
±3 % of current measured value
• Q = 1 to 15 %
±0.45 % o.f.s.
(all data under reference conditions)
The measuring device is calibrated and adjusted on
an accredited and traceable calibration rig . The
accuracy is certified with a calibration protocol.
H • Q = 20 to 100 %
±4 % of current measured value
• Q = 1 to 20 %
±0.8 % o.f.s.
(all data under reference conditions)
The measuring performance of the device is tested,
and a verification protocol confirms that the device
measures within the specified tolerance.
G Q = 1 to 100 %
±5 % o.f.s.
(under reference conditions) This version is subject to neither a calibration nor a
verification of measuring performance.
Accuracy of outputs
Current output
Accuracy Max. ±0.05 % o.f.s. or ±10 µA
Repeatability ±0.5 % of value for velocities > 1.0 m/s (3.3 ft/s)
Response time Typically < 3 s for 63 % of a given step change (in both directions)
Influence of medium
pressure
Air: 0.35 % of value per bar (0.02 % per psi) of process pressure change
