Following other advice I requested not to go through that rotating image machine in security but to have the manual pat down instead.
That is unusual advice.
Whilst I have been told that manufacturers do not approve the use of the "rotating image machine", I have never been told such a thing with Libre. In fact, my Libre have been through those machines multiple times with no issues.
Unfortunately, as I now have a pump, usually, I do have to avoid those machines and given my experience, I would never advise to refuse it unless really necessary.
I guess less people are traveling at the moment because the wait to be patted down can be very long so I always have to give myself at least 30 minutes extra to get through security.
I have also spent a very uncomfortable time with a very rude security person being dragged to another room because I "refused to conform to the security screening".
