Type 12S KWH meter

Can anyone tell me what the right meter is to use with a 240V 3-phase delta grid-tie?
I was sold a type 12S, "5-jaw" meter that only taps into 2 of the phases.
Is that right or is a 14S "7-jaw" that taps all 3 phases needed? Thanks

    It is sufffiecient for a 3 wire feed.

    On Edit:
    If it is a 4 wire feed then a 16S would be needed.
