Apex 150 is a specially designed wall-mounted energy meter for bulk power transfer points, where precise measurement and accurate revenue transactions are essential. Its modular communications options enable easy integration with existing automatic meter reading (AMR), supervisory control and data acquisition (SCADA), and substation automation systems (SAS).

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

Application

  • Grid and feeder metering

    Precise measurement of mass energy flow at grid and feeder points, for analysis and revenue collection

    Power plants/wind turbines/Solar generation

    Accurate measurement of exported energy, for revenue collection and billing
