If you want to control the direction your meter will count the power it accumulates, plan accordingly for which way you wire the top and bottom terminals of the socket. The meter globe is built for power to flow down from the top terminals from the utility, and out the bottom terminals to the load. Overhead rated sockets only have enough room for top-down wiring, and typically have a built-in hub or hub provision on the top for the service mast. Underground-rated sockets, have enough extra space to U-turn the wires inside. Dual-rated OH/UG sockets are just like UG rated sockets, except with the additional provision to attach a conduit hub on the top.
A customer-owned production meter that uses a utility-style meter socket, is typically wired in a manner, to count production as positive. Any meter whose purpose doesn't concern the utility, or whose purpose doesn't concern program with a policy that requires otherwise, is usually wired this way. Such as a Locus data logging production meter, that is built for utility meter socket housing. It is wired so the most common power flow direction, will cause it to count positive.
Depending on the application of this meter, there may be a specific reason why you would have to arrange your meter wiring the other way around. For instance, you may have an incentive program that requires such a meter, and that program may have a standard for it to be wired in the same orientation as a utility service meter. This way, power drawn from the utility, is assigned a positive sign, consistent with the utility's standards. Such a production meter, would count to the negative by design.
