3.3 Virtual reference for IFC 300 (C, W and F version)
The virtual reference option on the IFC 300 flow converter provides complete isolation of the
measurement circuit.
Benefits of virtual reference:
• Grounding rings or grounding electrodes can be omitted.
• Safety increases by reducing the number of potential leakage points.
• The installation of the flowmeters is much easier.
Minimum requirements:
• Size: ≥ DN10
• Electrical conductivity: ≥ 200 µS/cm
• Electrode cable: max. 50 m / 164 ft, type DS
