General information on Saia PCD® energy meters
Reliability directly after delivery from the factory
The design and production of energy meters in Murten are such that the meters also exhibit high
levels of reliability and durability even under extreme industrial conditions. The high quality standards
of the Swiss production site guarantee high accuracy and enable the production of MID-approved
energy meters, which have a guaranteed accuracy immediately following delivery and for their entire
calibration period. The approval means that the measured values cannot be doubted and can be used
across Europe for billing purposes.

Meters for converter connection
Through the use of current converters, costly shutdowns of entire machines for meter installation
are becoming a thing of the past. The replacement of an energy meter or current converter while the
system is running is possible with the consistent use of flap current converters, since the faulty parts
can be replaced easily without disconnecting the entire system from the power supply.
