The “Byram” B31 Three Phase meter was designed to meet today's most demanding commercial and industrial requirements.
The B31MOD offers a solution for DOE (Department of Energy) and IECC (International Energy Conservation Code) Chapter 4 section C405.12 Comprehensive energy monitoring and sub-metering in new and commercial buildings.
The “Byram” B31 represents one of the most modern mutifunction sub meter available today. Building on the still available platform of the B20 and B30 meters, the B31 includes many of the popular communications used today – All in one meter.
