Very similar questions have been raised recently in the forum. Have you done a forum search?

I have a similar issue running a AL1341 reading two words from SA4100.

When I try bit shifting it doesnt give the accurate value, have you been successful?

It appears you aren't trying to convert a number as much as parse it. You don't say what the values should be but google javascript parse and you should have a few examples

What does the data look like (show us the debug output) AND what should it look like?

If it is a buffer or an integer array, the node-red-contrib-buffer-parser node can probably do this in one go.
