Type 340 LW-LonWorks® BTU Transmitter
Brand: Badger MeterThe Series 340LW BTU transmitter is an economical, compact device for sub-metering applications requiring addressable network output capabilities using the LonWorks® protocol.
An economical, compact device for sub-metering applications that communicate via a LonWorks® network.
Calculates thermal energy in a closed pipe hydronic system by integrating the flow and temperature inputs.
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 closed pipe system
- Communicates via a single two-wire bus
- Compact cast epoxy body
