What instrument equipment needs to be calibrated for on-site construction? Are there any standard regulations? I know there are flow meters, safety valves, pressure gauges, and things like that, but I’m not from this field. I’d like to know more specific details. Thank you.

Refer to the \"Technical Specifications for the Construction of Petrochemical Instrumentation Projects\" SH/T3521----2007

Flow meters, thermocouples, thermal resistors, thermometers, pressure gauges, etc. need to be calibrated by a qualified metrology department, while transmitters (pressure transmitters, differential pressure transmitters, level transmitters, etc.) and various instruments in the control room can be calibrated by the installation unit itself.
