Bykski flow meter, flow direction?

[Jay85]

Instructions says flow left to right, looking @ screen.

Wonder if they assembled the impeller wrong way round?

Yeah thats what caught me out when i looked at it, i was thinking to myself have i got a dud here? I feel like they got their lefts and rights wrong way round lol... i looked at users from other builds with the same flow meter and they say by default its right to the left? God knows lol
