My answer presumed there was a running total on the meter, and thus
it was be'ein. But you're correct that I don't know enough about the
meter in question to assume that. The meter reader might have a display
to plug into the meter, or might even use a data connection to read it
from their office.

"Consequent" means gerama, not pesiq reishei, and "might" would make it
mutar. Like opening the door to a house that has a thermostat.
