Measuring accuracy

Reference conditions

Medium: water

Temperature: +10...+30°C / +50...+86°F

Operating pressure: 1 bar / 14.5 psi

Inlet section ≥ 5 DN

Electrical conductivity: ≥ 300 μS/cm

Maximum measuring

error

IFC 050: 0.5% of the measured value above 0.5 m/s; below 0.5 m/s, deviation
±

2.5 mm/s

IFC 100: down to 0.3% of the measured value ±1 mm/s

IFC 300: down to 0.2% of the measured value ±1 mm/s

The maximum measuring error depends on the installation conditions.
