@ProElec Submit your suggestion so I can give you the points!

Marc Rizkallah (asker) Apr 21, 2013:

@Tony Thanks for the clarification. That explains "de contrôle" which seems to fit that explanation quite well after all.

Tony M Apr 21, 2013:

check Normally, where the water enters the building, there will be a relaible accurate meter, usually provided by the water supply utility, which will be used as a basis for billing.
Within the premises, there may be individual meters, provided by the building's owner / occupier, to 'check' exactly how much water is being used by certain services — for example, domestic water vs process water, or how much is used for the laundry vs the kitchen in an hotel; or how much is consumed by some particular machine. This is quite common in industry or in shared premises; for example, in the flats where I once lived, the landlord had fitted a meter to the feed to each unit, so that he could apportion the overall water bill correctly to each resident.

J'sais toujours pas... J'ai trouvé nombreux exemples de "compteurs d'eau" ou "compteurs divisionnaires" -- mais aucun exemple de "compteurs d'eau *de contrôle*" -- ma question c'est, quelle est la différence (s'il y en a une!) entre "water meter" (compteur d'eau / compteur divisionnaire) et CHECK water meter ("de contrôle"?)

Proelec Apr 11, 2013:

Pour moi ... il devrait s'agir ici d'un "compteur d'eau de contrôle" encore parfois appelé "compteur divisionnaire". Nombreux exemples sur Google.fr.

Tony M Apr 11, 2013:

Another idea... Wait!
A 'check meter' can also be used to verify local consumption at a certain point or to a certain machine; this would then be as distinct from the main meter (usually sealed and provided by the water supply authority), and would probably be installed by the owner of the property or plant.

You ought to be able to tell from your wider context; if it is indeed the main meter for the incoming supply, then suggestion #1 remains plauisble; however, if it comes later in the circuit, that sort of rules out #1 and makes #2 more likely.

anti-retour plutôt ... mais attendez l'avis des francophones ;-)

Marc Rizkallah (asker) Apr 11, 2013:

Hm... Bel astuce Tony. Qu'en penses-tu, alors:
compteur d'eau de non-retour?
ou compteur d'eau anti-retour?

Tony M Apr 11, 2013:

check A 'check valve' is intended to stop back flow, for example, so perhaps it is that srt of thing? Not uncommon in a supply meter, since return flow into the main is usually forbidden. And see the mention of this on your plan...
