Most situations in the plant environment require "two watches"
How much is accuracy worth? It often depends on how catastrophic the consequences of inaccuracy are.
In the processing plant, it’s generally understood that if it comes down to checking once or checking twice, checking twice is the better option to obtain a more accurate reading. However, with staffing limitations spreading plant workers thin already, that can pose a major challenge.
To identify potential errors in the plant environment, instrumentation and control professionals have an important job to work with processing counterparts to ensure everything is run smoothly and correctly.
