340 BN\/MB Btu Energy Transmitter","The Data Industrial® 340 BN\/MB Btu Energy Transmitter from Badger Meter is an economical, compact device for sub-metering applications utilizing the BACnetTM or Modbus® communications protocol. The 340 BN\/MB Btu Energy Transmitter calculates thermal energy using the signal from a flow sensor installed in a hydronic heating or chilled water system, and the signals from two 10k Ω temperature thermistors, 100 Ω RTDs, or 1000 Ω RTDs installed in the system's inlet and outlet points. The flow input may be provided by any Data Industrial sensor and many other pulse or sine wave signal flow sensors. The on-board microcontroller and circuitry make precise measurements and produce accurate, drift-free outputs. The 340 BN\/MB Btu Energy Transmitter is programmed using Badger Meter Windows® based software. Calibration information for the flow sensor type and pipe size may be preselected or entered by the user in the field. While the unit is connected to a PC or laptop computer, real-time flow rate, flow total, temperatures, energy rate, and energy total are available. The 340 BN\/MB Btu Energy Transmitter features three LEDs to verify the sensor input signal, network link and pulse output. The 340 BN\/MB Btu Energy Transmitter communicated via RS-485. The compact cast epoxy body measures 3.65 x 2.95 inches (93 x 75 mm) x 2.95 and can be easily mounted on panels, DIN rails or enclosures.
