Series 380 Btu Meter The Data Industrial® Series 380 Btu meter from Badger Meter is an all-in-one energy usage package for monitoring hydronic heating or cooling systems. The Series 380 Btu meter 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 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 the application. These minimal connections help simplify installation and save time.","The Series 380 Btu meter offers cost savings over other systems offered on the market today. The integration of flow and temperature sensors, along with metering components provide a single solution for metering making it possible to meter energy where it hasn't been cost effective before.
