Sulfuric acid pipeline flow meter, with static discharge bonding terminals provided; the meter has two wires that are not connected to anything
Thread Content
May I ask, is there any problem with the status shown in the image? If so, how should it be corrected?
Generally, there is one grounded terminal; if the device has two terminals, they may be the working terminal and the protection terminal, with the latter needing to be connected to the protection ground at the installation site
If there are multiple electrodes or a grounding ring, only protective grounding is required
The ground wire can be fixed to the static bypass ear
Connect the two black wires of the flow meter to the grounding rings welded on the pipes on either side, and that’s it. This keeps it at the same potential as the work area and safely. No potential difference means no interference.
