UNCTIONALITY

The SGM1400-B Series meter supports an extensive feature set comprising 

metrology related functions, support of tariffs, load profile, power quality data, 

etc. The meter is similar to a complete energy meter (not just an electricity meter) 

when coupled with appropriate ZigBee communication devices for metering gas.

Multipurpose Energy Metering

The SGM1400-B Series meter supports the storage and operation of multiple 

energy types that are measured directly by the meter. Electrical observables are 

measured directly by the meter. 

Preferred measurements can be selected to be defined and stored independently 

for each storage operation. These measurements include:

• demand calculations,

• time-of-use storage, and

• load profile storage.

Instantaneous Measurements

The SGM1400-B Series meter supports measurement of multiple electrical 

parameters. The following instantaneous measurements are available for each 

measuring element. These instantaneous data values are calculated and updated 

every momentary interval (approximately one second).
