Type 340 N2 Metasys Btu Transmitter

Brand: Badger Meter

The Series 340N2 BTU transmitter is an economical, compact device for sub-metering applications using Johnson Controls Metasys Network Companion™ and Facilitator™ Supervisory Systems.

An economical, compact device for sub-metering applications using Johnson Controls Metasys® Network Companion and Facilitator Supervision System.

Calculates thermal energy in a closed pipe hydronic system by integrating the flow and temperature inputs.
Features
  • On-board microcontroller and digital circuitry make precise measurements and produce accurate, drift-free outputs
  • Accepts the signal from any Data Industrial raw pulse flow sensor, as well as many other pulse and sine wave devices
  • Calculates thermal energy by measuring liquid flow in a closed pipe hydronic system by integrating the flow and temperature inputs
