I was having this "material empty" issue, too. I turned off the flow sensor but the print got so filled with webs that I had to turn it back on. I am printing with ordinary PLA from MatterHackers on a spool in back of the machine on a roller mechanism. In my desperation to deal with the material empty problem, I decided that the S5 wanted the spool to hang from the back. I took off the Ultimaker "tough PLA" spool and set it directly in back of the machine (for no reason other than I was too busy to put it away) and put the MatterHacker PLA hanging off the spool holder. Since then, I haven't gotten the error message. (It's been about a week.)
Is there a sensor in the Ultimaker spool? I have no idea. But no error message is good enough for me. (Fingers crossed that I haven't jinxed the whole thing now.) Of course, that spool of tough PLA is going to go bad from just sitting around there...

I would not say always. Here would be the thought behind that. Find out what angle your printer can do without supports. For instance, this is a two colour print without supports.

That does not look good. Can you check a few things to rule out some causes? Can you check if you're in the latest version of the firmware? We improved the end of filament detection a lot since the fi

On the main screen hit the gear icon. then go to the settings button. Flow sensor will be in there....second from top.

After watching it finish a layer to find out when the error is happening, it's the PVA extruder that's triggering it. It has been raining and there is an open window near the machine, so this lends some support to the wet PVA theory.
edit: I swapped in a brand new spool of PVA and the error stopped
