Issues related to safety barriers when connecting flow meters to the DCS cabinet.
Thread Content
Once, while the company’s vehicle was in use, lightning struck the ground, and as a result several of the safety guards on the flow meters were damaged. Later, those flow meters were connected directly to the base, without using the safety guards, and they have been used in that way ever since. I’m not sure what effects this might have
Apart from not meeting safety regulations, it does not affect the measurements. :lol :lol :lol :lol
It depends on the type of position; safety barriers must be installed in hazardous positions. Grounding must be standardized.
Is the flow meter flameproof? Explosion-proof instruments may also require safety guards in some situations. This is safety; safety first
Thank you all. We produce esters, and we’ll install it in a while.
Our approach is to install safety barriers at both ends of the flow meter; after all, flow data can be very important, and losing it is troublesome
If the flow meter is intrinsically safe, it may not be necessary to use a safety barrier; however, if it’s flameproof, it’s recommended to use one anyway, as it would be problematic if the device gets damaged
Safety first; it’s better to install safety guards.
Is the on-site flow meter explosion-proof or intrinsically safe? If it is explosion-proof, no safety device is necessary; but if it is intrinsically safe, a safety barrier must be installed on the DCS to form an intrinsically safe circuit.
Install it properly; it’s not worth it if there are fewer keypins
If your flow meter is intrinsically safe, no safety barrier is required； If your flow meter is intrinsically safe, a safety barrier must be used; its function is to prevent unsafe signals from the hazardous area (control room) from reaching the safe area. You are lucky that no accident occurred; if one had happened and led to an explosion, someone would have to take responsibility. Safety issues cannot be taken lightly. If there is a problem with the safety barriers burning out, it’s possible to check whether the grounding is proper and whether the wiring is correct
