Flow (5 ... 100 cm/s): ±2 cm/s
Temperature: 0.5 K
Flow (5 ... 100 cm/s): ≤ ±5 % of end value of measuring range
Flow (>100 ... 175 cm/s): ≤ ±10 % of end value of measuring range
Temperature: ≤ ±1,5 K
Including non-linearity, hysteresis, zero offset and end value deviation (corresponds to
measured error per IEC 61298-2).
The accuracy of the flow switch is dependent on the thermal conductivity and the contamination
of the probe.
