DP Level & Flow
What this tool does
Rate and total from a pulse K-factor, plus the linear current that rate would drive. 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 Flow totalizer when this is the job: Rate and total from a pulse K-factor, plus the linear current that rate would drive. That is usually a level or flow calibration, a bore check, or a valve you are about to size.
Step-by-step
- Open Flow totalizer from the tool list.
- Fill Units, K-factor, Frequency, Frequency span 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
- Units
- Imperial or metric. Pick one and enter every other field in that system.
- K-factor
- Pulses per unit volume from the flowmeter sheet.
- Frequency
- The pulse rate you are measuring.
- Frequency span
- Frequency span is the value you read from the instrument, the drawing, or the job record. Enter it in Hz.
- Pulse count
- Pulse count is the value you read from the instrument, the drawing, or the job record.
- Rate LRV
- Rate LRV is the value you read from the instrument, the drawing, or the job record.
- Rate URV
- Rate URV is the value you read from the instrument, the drawing, or the job record.
Results
- Result
- The reported value for Flow totalizer. 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 Flow totalizer as a substitute for the site procedure or the manufacturer data.
