340 BN/MB BTU Energy Transmitter
Brand: Badger MeterThe 340 BN/MB BTU Energy Transmitter is an economical, compact device for sub-metering applications using the BACnet or Modbus® communications protocol.
An economical, compact device for sub-metering applications.
Calculates thermal energy using the signal from a flow sensor installed in a hydronic heating or chilled water system, and the signals from two 10 kΩ temperature thermistors, 100 Ω RTDs or 1000 Ω RTDs installed in the system’s inlet and outlet points.
Features- On-board microcontroller and circuitry make precise measurements and produce accurate, drift-free outputs
- Calibration information for the flow sensor type and pipe size may be preselected or entered by the user in the field
- Calculates thermal energy using the signal from a flow sensor installed in a hydronic heating or chilled water system
- Compact cast epoxy body
