The Badger Meter 380DS Impeller BTU System 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 materials of construction include polycarbonate housing for electronics, EPDM o-ring, tungsten carbide shaft, stainless steel impeller, brass tee, and Ketron bearing.
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.
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.
All Series 380 BTU meters are equipped with BACnet and Modbus protocols as standard features. The protocol of choice can be selected and set up in the field at the user's discretion. These common protocols allow for quick and easy commissioning while gaining valuable application data beyond energy total. Information such as Flow Rate, Flow Total, Energy Rate, Energy Total, Temp 1, Temp 2, and Delta T can all be transmitted on the RS-485 connection.
If the RS-485 is not required for the application, a simple scaled pulse output is available. The pulse output would represent energy total and can be set in various units of measure. The pulse output is an open drain scaled pulse output that is compatible with a variety of PLCs, counters and the Badger Meter 350 wireless system, so the unit is easily compatible with most inputs.
