Powerful variable analysis and great communication capabilities: this is the strength of WM4 96

Official watt-hour meter interface. The 3 interfacing methods of WM4 96 are:

• Direct measurement for the power quality analysis (LV or MV/HV connection).

• Indirect energy and power measurements by means of official Watt-hour meters

(LV or MV/HV connection).

• Direct measurements of the instantaneous variables (LV connection) and indirect

measurements of the energy variables (LV or MV/HV connection).

• Energies-water-gas and instantaneous variables readable on the display of your GSM mobile

phone giving you maximum control freedom, saving time and money.

• Alarms transmitted as soon as they occur via GSM or analogue modem notifying the plant

abnormal conditions.

• Data logging and stamping of up to 8 programmable instantaneous variables for a time duration

up to 90 weeks with date and time references to build up the history of your electrical installation.

• Wm4Soft network communication software to download, manually or automatically (via RS485-

analogue modem-GSM modem) up to 2Mb data stored in the WM4 96. This information can be

simply plotted in an Excel spreadsheet.

• Continuous data stamping and communication: RS232, RS485, modem, GSM.

• Powerful data acquisition by means of Wm4Soft and mobile phones wherever you are.

Mains quality analysis because

the harmonics are cause of

load failures and production

stop.

Load profile display with

alarms to keep the energy con-

sumption and power cost

under full control.
