Series 380 BTU System provides a low-cost solution for metering cold or hot HVAC systems. The 380 measures flow and temperature differential to accurately calculate energy usage. With BACnet, Modbus RS-485, or scaled pulse output, it can interface with many existing control systems. The rugged design incorporates an impeller flow sensor and two temperature probes, one mounted in the flow sensor tee and the other on either the supply or return line, depending on the application. Commissioning can be done in the field via a USB computer connection. Setup includes energy measurement units, measurement method, communication protocol, pulse output control, fluid density, and specific heat parameters.
