INTRODUCTION
The Data Industrial® Series 380 Btu System from Badger Meter provides a low cost solution for metering cold or hot systems.
The 380CS/HS can accurately measure flow and temperature differential to compute energy. Utilizing BACnet™ or Modbus®
RS-485 communications protocols or a scaled pulse output, the Btu System 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 installation requirements. These minimal connections help simplify installation and save time.
The main advantage of the Series 380 Btu System is the 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.
With this system, it will be possible to meter energy where metering had not cost effective.
Commissioning of this meter can be completed in the field via a computer connection. Setup includes energy measurement
units, measurement method, communications protocol, pulse output option, fluid density and specific heat parameters.
Cold Service (380CS)
Designed for operating in fluid temperatures of -4°F to 140°F (-20°C to 60°C). Refer to the pressure vs. temperature chart on
page 11.
Hot Service (380HS)
Designed for operating in fluid temperatures of 40°F to 260°F (4°C to 125°C). Refer to the pressure vs. temperature chart on
page 11.
Series 380
The 380 combines an electronics package with a PEEK sensor probe inserted in a 3/4", 1", 1-1/4", 1-1/2" and 2" proprietary cast
bronze pipe tee with threaded NPT connections.
