Regarding the unit issue of the tank area level gauge displayed on the DCS?
Thread Content
The unit used for indicating remote liquid levels is generally either percentage or mm. Using percentages is convenient, intuitive, and easy to communicate about; whereas using mm makes it easier for handovers and calculations. Do any of you have any suggestions regarding the unit to be used for indicating liquid levels?
It should be mm, that’s how we can know the actual value. The percentage is represented by a vertical bar on the tank, which is filled with color; the color intensity changes according to the numerical value.
By *habit, no matter how it’s set, over time one becomes* accustomed to it
There’s no good advice here; both meet the standards, so you can choose whichever one you want.
Percentage, mm, or the converted volume value can be set as required.
It depends on the practices of your company; if it’s about liquid level monitoring, then MM
There are no specific requirements for my experience; it can be adjusted according to actual needs. We initially used percentages, but later changed to mm.
Why was it changed later? Is there any reason?
Multiple options can be set; all are calculated values, including percentages and volume amounts.
We are using the method on the first floor; it’s better to use millimeters. Using percentages can be inconvenient if one can’t remember the range.
Our company’s tank area is of type MM, and it has a filling bar that changes as the volume varies.
