1.- INTRODUCTION.
CIRWATT is a multi-purpose three-phase, four quadrant, digital meter. Its great
versatility is its main feature, allowing it to adapt to the needs of each user.
It has been especially designed for installations where the electro-mechanical meters
do not meet current requirements. It is specifically for those installations that require a
meter with a tariff system or where electricity billing is done by using load profiles.

3.- SAFETY LEVELS (Seals)
CIRWATT has the necessary seals to ensure that the meter is not tampered with.
These seals must always be attached once the meter is installed.
•
Terminal cover seals. These are attached
once the equipment has been installed These
seals prevent the modification of the meter
connection.
•
Button seal. Bill closure and equipment
RESET operations are protected by these
seals.
•
Label Seal. This prevents the equipment
features label from being changed.
(Transformation ratios, integration period, type
or market and area of installation).
