Molbloc flow rates are shown in the Molbox1+ user manual in a series of tables. The flow rates can change over time and not all gases in these tables are available to have calibrations performed in. It can also be difficult to understand what flow rates can be achieved based on the specific type of calibration that is being used and/or if your application will utilize vacuum or not (sonic Molbloc's only). User manuals will be periodically updated, but this article will be used to help update some of this information quicker and also provide some alternative views of the tables that some might find easier to understand. Attached are separate spreadsheets that show some updates for laminar and sonic molbloc's separately.
Laminar flow ranges are fairly easy to understand, so the only updates in the attached spreadsheet would be for flow rate changes.
Sonic flow rates as much more difficult to understand, so you will see both updates and different table formats in separate tabs within the spreadsheet for sonics. Most tables have also been reduced down to the 5 gases we currently offer calibrations in and will be named "*_5 gases". One new table shows all all previously published gases in an extended format and is named "*_all gases". There is also some info about how to calculate flow rates at various pressures in different gases at the bottom of the first tab. The primary changes are to show what the new maximum flow rate would be on standard pressure calibration type at the newer 600kPa pressure. The new tables also help to show flow rates based on the calibration type whereas legacy tables did not show this. Some of these updates and a newer table format will also be included in an update to the official Molbox1+ user manual that can be downloaded on our website.
Note: flow rate updates might only apply when using the latest Molbox1+ model with your Molbloc's. For those using older Molbox1, refer to original user manual and confirm flow rates using your Molbloc calibration reports.
Excel spreadsheet's of the tables are attached below, but here is a snap shop of the tables for each discussed above that are likely the most useful:
