The concept
The system does not measure the actual inflation pressure in the tires.
It detects a pressure loss in a tire by comparing the rotational speeds of the individual wheels while moving.
In the event of a pressure loss, the diameter and therefore the rotational speed of the corresponding wheel change. This is detected and reported as a flat tire.
