Item 5746 is the Uni-syn, which has been around for quite a while.  These work fine, but have their drawbacks, and some people don't care for them.  The other three items appear to be variants of the same device.  If this is the Schleyer flow measuring device, I've heard good reports but haven't used one myself.
