1 Grounding ring number 1
Grounding ring number 1:

• 3 mm / 0.1" thick (tantalum: 0.5 mm / 0.02")

• 3 mm / 0.1" thick
• Prevents damage to the flanges during transport and installation
• Especially for flow sensors with PTFE liner

• 3 mm / 0.1" thick
• With cylindrical neck (length 30 mm / 1.25" for DN10...150 / 3/8...6")
• Prevents damage to the liner when abrasive liquids are used

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.
Figure 3-3: Virtual reference
Minimum requirements:
• Size: ≥ DN10
• Electrical conductivity: ≥ 200 µS/cm
• Electrode cable: max. 50 m / 164 ft, type DS
