Measuring accuracy
Reference conditions

Medium : water
Temperature : 10…30°C / 50…86°F
Operating pressure : 1 bar / 14.5 psig
Inlet section : ≥ 5 DN
Electrical conductivity : ≥ 300 μS/cm
Flow conditions similar to EN 29104

Maximum measuring error :

These values are related to the pulse / frequency output.
Related to volume flow (MV = Measured Value)
With IFC 040 converter:
v < 1 m/s / 3.3 ft/s: ± 5 mm/s
v > 1 m/s / 3.3 ft/s: ± 0.5 % of MV
With IFC 100 converter:
DN2.5…6: ± 0.4% of MV + 1 mm/s
DN10…1200: ± 0.3% of MV + 1 mm/s
With IFC 300 converter:
DN2.5…6: ± 0.3% of MV + 2 mm/s
DN10…1600: ± 0.2% of MV + 1 mm/s
DN1800…3000: ± 0.3% of MV + 2 mm/s
The additional typical measuring deviation for the
current output is ±10 μA.
The maximum measuring error depends on the installation
conditions.
For detailed information refer to Measurement accuracy on page 21

Repeatability : ±0.1% of MV, minimum 1 mm/s
