The series 380 Btu systems provide a low cost system for metering cold or hot systems. The 380CS/HS can accurately measure flow and temperature differential to compute energy. Utilizing either BACnet or Modbus RS 485 communications protocols or a scaled pulse output, the Btu meter can interface with many existing control systems.
The rugged design incorporates an impeller flow sensor and two temperature probes. One temperature probe is conveniently mounted directly in the flow sensor tee. The second temperature probe is placed on either the supply or the return line depending on ease of installation for the application. These minimal connections help simplify installation and save time.
Commissioning of this meter can be completed in the field via a computer connection or setup at the factory with the customers requirements. Setup includes energy measurement units, measurement method, communication protocol, pulse output control, fluid density and specific heat parameters.
