Options
(grounding
straps)
Acceptable for conductive unlined pipe
Grounding straps provided at no cost
Reference Elec-
trode
Same material as measurement electrodes
Sufficient grounding option when process fluid conductivity is greater than 100
microSiemens/cm
Not recommended in electrolysis applications, galvanic corrosion applications,
applications where the electrodes may coat, or non-conductive pipe.
Grounding
Rings
Low conductivity process fluids
Cathodic or electrolysis applications that may have stray currents in or around
the process
Variety of materials for process fluid compatibility
Lining Protec-
tors
Protect upstream edge of sensor from abrasive fluids
Permanently installed on sensor
Protect liner material from over torquing of flange bolts
Provide ground path and eliminate need for grounding rings or reference elec-
trode
Required for applications where Flexitallic gaskets are used
