Flow Meters?

How do your flow meters work? How are they better than the GHL meters?
Thanks

I’m guessing by the way they look their using some kind of paddle wheel? How often do they need to be cleaned? Can you take them apart? Where are they made?
Thanks

They are a paddle wheel design (200 is observably different, but still looks to use some kind of paddle). They can be easily disassembled for cleaning, though how frequently will depend on your specific application.
