TARIFF ENERGY METER-SINGLE PHASE
MER
MER is an active energy meter; it is static single
phase meter which means that it can substitute the
import and export meter and the tariff time switch.
MER makes the direct measurement of active import
energy, valid for time discrimination.
Period closing by means of button, 6 digit display.

The optimum solution for Household metering.
The MER B is an electronic meter for the measurement of
active energy which allows the best cost/benefit ratio to
be found for household meters. It provides the advanta-
ges of state-of-the-art electronic measurement techno-
logy. The meter has an LCD type display with large,
clear digits.
The measurement of active energy is class B with stable
behaviour throughout its curve. In order to be able to
connect with AMR systems the meter has an optional
pulse output, an RS485 interface and a comfortable
auxiliary relay remotely.
