On the DCS, set key parameters such as flow rate and pressure to trigger alarm in case of sudden changes
Thread Content
Some monitoring tasks are carried out by the DCS; by setting key parameters such as flow rate and pressure to trigger alarms in case of sudden changes on the DCS, it is possible to effectively reduce the losses caused by unexpected pump shutdowns and malfunctioning pressure sensors. Do anyone have any suggestions regarding this approach?
We have been using these things for a long time
This can reduce the workload on the operators, while also alerting them to any changes in the data
The original poster is right; this technology is already very widespread, so there’s no need to discuss it further. If you haven’t used it yet, hurry up and do so
It mainly allows problems to be identified in a timely manner. Protect the safety of equipment and people
It has been in use for a long time; now some DCS designs come with this alarm as a standard feature.
It is usually set to the default value on DCS. It’s very widespread. There’s no need to discuss it anymore. Use it quickly!
DCS systems typically have upper and lower limit alarms for parameters, which are what are known as process alarms. Alarms for phenomena such as pump shutdown or sudden valve closure, as mentioned by the poster, are generally not installed on the DCS but rather on the SIS and ITCC, which ensures higher reliability!
