WM4 96 is a Universal Utility meter and Power Quality

Analyzer. This high-tech instrument has been developed to

meet the most advanced application needs. WM4 96 offers

to the user many advantages and solutions that can be

summarised in:

• Load failure prevention by:

quick assembly and maintenance using Plug and Play

modules

harmonic analysis (A/V) with source detection and

control; up to 4 alarms for a powerful variable control;

alarms logging and data stamping.

• Remote control facilities: up to 4 pulse outputs, RS485

port (Modbus RTU), RS232 port.

• Load profile display to keep supply costs under control.

• Energy cost allocations with independent import/export

kWh/kvarh and kWh/kvarh multi-tariff management

• Water and gas metering and communication using the

same instrument.
