DP Level & Flow
What this tool does
Hydrostatic level LRV and URV for wet-leg or dry-leg differential pressure. This page says what the tool is for, in plain language. The working formula stays on the signed-in tool.
When to use it
Open DP wet-leg / dry-leg level when this is the job: Hydrostatic level LRV and URV for wet-leg or dry-leg differential pressure. That is usually a level or flow calibration, a bore check, or a valve you are about to size.
Step-by-step
- Open DP wet-leg / dry-leg level from the tool list.
- Fill Level span height, Height unit, Process specific gravity, Wet-leg height from the instrument, the drawing, or the job record. Use the unit shown beside each field.
- Fill the remaining fields the same way. Skip a field only when the screen marks it optional.
- Run Calculate when that control is on the page, then read every result row and any warning.
- Check the result against the site procedure and the manufacturer data before you change a range, a wire, a setpoint, or a weight.
- This help page is public. Opening the tool still requires a Pro session.
Inputs
- Level span height
- Level span height is the value you read from the instrument, the drawing, or the job record.
- Height unit
- Choose the Height unit that matches the instrument, the drawing, or the job. Choices include inches, metres.
- Process specific gravity
- Process specific gravity is the value you read from the instrument, the drawing, or the job record.
- Wet-leg height
- Wet-leg height is the value you read from the instrument, the drawing, or the job record.
- Wet-leg specific gravity
- Wet-leg specific gravity is the value you read from the instrument, the drawing, or the job record.
- HP tap offset
- HP tap offset is the value you read from the instrument, the drawing, or the job record.
- Static blanket pressure
- Recorded for the job. It must not change LRV or URV.
Results
- Result
- The reported value for DP wet-leg / dry-leg level. Use the unit printed on that row.
- Warnings
- A warning means an entry is incomplete or outside what this tool will stand behind. Recheck the inputs and the site procedure.
Common mistakes
- Using the wrong specific gravity, or forgetting a wet leg, a seal fill, or a blanket pressure.
- Mixing a head unit with a pressure unit without reading the unit on the screen.
- Sizing from a flow or a differential that is not the one in the line.
- Do not treat a result from DP wet-leg / dry-leg level as a substitute for the site procedure or the manufacturer data.
