What is the approximate flow rate sensor pulse limit now in the new 2.2.1 release for a Raspberry pi3B and zero2W ?

The poll timeout has been reduced to 5ms, so theoretically it can handle 200 polls per second, and accounting for the sampling theorem, it can handle pulse rate of 100 clicks per second. The 5ms timeout can be further reduced, but I assume the ability to handle 100 clicks per second is probably more than sufficient.

What about OS 2.3, has its timeout also been reduced to 5ms ?

The limit was only an issue on OSPi, because the previous firmware had a poll function that uses a 50ms timeout. On OS 3.x and 2.3, there is no such poll function, so it doesn’t affect them.
