Installation
Grounding Instructions
For correct operation of the meter, it is essential that the
sensor and the liquid are at the same electrical potential.
Always connect the sensor and the converter to ground.
Grounding for metallic pipes
Grounding with insulating pipe
Grounding with cathode protection pipe
If the sensor is to be mounted on a pipe made of an
insulating material, it is necessary to perform the follow-
ing:
•
Install two metallic grounding rings between the sen-
sor flanges and the counter flanges of the pipe line
or:
• Use a sensor with the additional grounding electrode.
If the sensor is to be installed in piping with cathode pro-
tection, it is necessary to perform the following:
•
Insulate bushings to isolate the bolts.
• Install metallic grounding rings to ground the liquid
and use insulating gaskets between the rings.
