The Badger Meter Model 340BN Btu Transmitter is an economical, compact device for sub-metering applications that utilize the BACnet® communications protocol. The Model 340BN calculates thermal energy using the signal from a flow sensor installed in a hydronic heating or chilled water system, and the signals from two 10kohm temperature thermistors or 100O RTD's installed in the system's inlet and outlet points.
