Data Loging

The RM Series provides data storage in non volatile memory of capacity 200 KB. The logs can be retrived via RS 485 port. As default all the basic parameter are stored at 15 min Interval.

Software Integration

The meters can be integrated with an Energy Mangement or SCADA system to provide remote display of all measured parameters and meters configurations. The meter communicates on MODBUS RTU protocol via RS 485 port.
