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. Using 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.
The main advantage of the Series 380 BTU meters is the cost savings over other systems offered on the market today. The integration of flow and temperature sensors provide a single solution for metering. With this system it will be possible to meter energy where it has not been cost effective before.
Commissioning of this meter can be completed in the field via a computer connection. Setup includes energy measurement units, measurement method, communication protocol, pulse output control, fluid density, and specific heat parameters.
