Grotesques liquifiers number per squad?

How many liquifier guns can grotesques have per squad?

I.E. Wracks can have 1 liquifier for every 5 wracks in a squad.

I see in the codex it just says one, but not in every 3 or 5 or whatever and I dont see a faq on it either. Is it just plain 1 in a squad no matter the size?

Thanks

Only one liquifier per squad, unless the haemonculus has one.
