Multi Function Meter

Multi Function Meter

Multi Function Meter 3400 is the latest product in the SANDS Energy Management Solutions. For any industry irrespective of their domain, the need of the hour is Energy Management System. One has to know the approximate energy usage that each one of the various departments consumes on daily or monthly basis. For this purpose, a cheaper, feature-rich Multifunction Meter would suffice in place of a full blown Energy Meter. MFM 3400 is one such meter that measures all the necessary electrical parameters for Energy Management System like Power, Power Factor, Energy Import, Energy Export at 0.5S accuracy. Using Industry standard Modbus RTU protocol, any DCU can collect the parameters list from the MFM 3400 through RS485 Interface.
