How to determine if a gauge is functioning properly
Thread Content
During the production process, various instruments are definitely used to guide production. How should we determine whether the gauge readings are accurate?
It’s normal to be in working mode generally. If any alarms or abnormal messages appear, that is abnormal. As long as it’s not abnormal, then it’s normal. It is impossible to determine whether it is normal or not when it is shut down.
On-site comparison, operational experience, material balance, heat balance.
First, it is necessary to ensure stability and clear display; comparisons can be made with relevant instruments, as well as based on relevant process parameters...........

Combine one’s own experience and on-site process requirements with the feedback provided by the operators.
This still relies on experience; it is mainly based on the pressure gauges and thermometers on site, as well as comparisons with other instruments in the same system. Generally, it is rare for multiple instruments to fail at the same time.
1. Consider the process relationships before and after to make judgments; 2. Compare data from remote sites; 3. Conduct verification tests; 4. Ensure stable alarms, accurate display, and flexible operation
This should be considered from two aspects: one is the process, and the other is the instrumentation. When there are no issues with the process assessment, it should be evaluated from an instrumentation perspective.
