About quadlogic controls

Founded in 1982,

Quadlogic is the most widely specified electric submetering system company in New York and Ontario, CA.  In New York, Quadlogic is vertically integrated, offering complete submetering solutions including equipment, field service, and billing services. Quadlogic holds over a dozen patents related to electric metering and remote measurement and control of power consumption.

Quadlogic submetering systems are installed in multi-tenant commercial and residential buildings nationwide, including The Mall of America, The Chrysler Building, The Plaza Hotel Condos, 432 Park Ave, One West 57 St., JFK Terminal 5, Gehry Downtown, and many other prestigious properties.  The company’s Powerline Carrier data communications technology allows communications over the existing building electrical network, eliminating the need for data wiring and radio frequency emissions.

The company’s systems are deployed widely, with hundreds of thousands of Quadlogic submeters in the United States. Quadlogic is an OEM supplier to GE. Quadlogic meters can log pulses from water, gas, BTU, and other meters, thus enabling remote reading and billing for all services.

Quadlogic’s Energy Guard electricity anti-theft systems are in service throughout Jamaica and Mexico, and pilots are underway in many additional markets.
