I would ask the water company what they require.


I was just told "any one that meets the cold water supply regulations"
and a link to the OPSI web site. Unfortunately that does not go into
detail about classes, so I am waiting for elaboration from the water
co.

Otherwise, here's a cheap one from a respectable supplier:

That's the one I saw, which started this particular ball rolling.

Thanks.

I would ring BES. I would just confirm if they are WRAS approved, which
implies suitable for domestic potable water, though their description
suggests they are.

No idea what the Class designation is - possibly, at a wild guess, teh
accuracy as that's the only thing I can think that may be affected by
orientation of a jet based meter - as you say, if so, Water Co would
probably be the best bet as it's them who care.

Cheers
