I was wondering if anybody knows of some revenue grade power meters that are able to communicate with VTS. Meters similar to the SEL 735.

Thanks,

Would one of the following be helpful: https://buildingcontrols.honeywell.com/literature/67-7566_Submeters_Quick_Selection_Guide.pdf

Page 5 has the following table:

Protocols available†
01 - EZ-7, EZ-7 Ethernet;
02 - Modbus RTU, EZ-7 Ethernet
03 - BACnet MS/TP, EZ-7 Ethernet
04 - EZ-7, Modbus TCP/IP;
05 - EZ-7, BACnet IP
06 - Modbus RTU, Modbus TCP/IP
07 - LonWorks TP, EZ-7 Ethernet
08 - LonWorks TP, Modbus TCP/ IP
09 - EZ-7, EZ-7 Ethernet with modem
10 - EZ-7, Modbus TCP/IP with modem
11 - EZ-7, BACnet IP with modem

I'd suggest meters with Modbus TCP/IP connectivity are most likely to work well.
