Head arrangement

For vertical tanks, you cannot specify anything here. The program always assumes convex heads for vertical tanks.

As soon as you have confirmed your input with <Enter> or when you leave the input field, all values are recalculated and updated.

First, enter a reasonable filling level between 0 and total inside height of the vessel.

Then enter the desired total liquid volume and specify the filling level as being calculated:

The filling level is now calculated!

First enter all input data as described in „General input“ to create a bearing graphic for your storage tank. Then perform a parametric study.

Enter values from the lowest filing level to the highest filling level and select the volume as target value:

Click on Start and you will receive a table with the calculated results. If you have MS EXCEL installed, simply select ‘Export to MS EXCEL’ and you will get a filed in EXCEL sheet with the results.

Select Graphics / 2-D graphic and you will get a bearing graphics immediately.

The bearing graphics from Creating a bearing graphic in the ATLAS system does only allow an estimation of the filling volume. To receive a more exact bearing chart, export the values to EXCEL

This values you can also use to create a curve for a fast evaluation with a dipstick. (s. Creating a bearing graphics in MS EXCEL)

Highlight the fields with the values and select “Insert Charts”.

Use Scatter Charts – Line.

You may then edit the table to meet your requirements:

If you are not using EXCEL but another spreadsheet program (e.g.  Open Office, Libre Office), you may as well use the data from the TKL calculation.  :

Save the results as CSV data  file.
