Badger® Series 340N2 METASYS® Compatible Energy Transmitter Installation & Operation Manual 872033 BadgerMeter, Inc. Rev.
Introduction The Badger Meter Series 340N2 Btu transmitter is an economical, compact device for sub-metering applications using Johnson Controls Metasys® Network Companion™ and Facilitator™ Supervisory Systems. The Badger® Series 340N2 works in conjunction with a flow sensor and two temperature sensors to calculate thermal energy by measuring liquid flow and inlet and outlet temperatures in a closed pipe system. The Series 340N2 requires two 10 kW thermistors for temperature input.
Sensor Wiring All flow sensor types connect to the four terminal header labeled “Sensor Input”. Series 200 Connect the red wire to Series 340N2 Sensor signal (+), connect the flow sensor black wire to Series 340N2 Sensor signal (-) and the bare wire to shield. SDI Series (standard pulse output option) Connect SDI number 3 sensor signal to the Series 340N2 transmitter sensor signal (+) and the SDI number 2 sensor common terminal to Series 340N2 transmitter sensor signal (-).
Temp 2 Mat Temp 1 10KΩ Thermistors Sample Sensor Wiring Diagram Thermistor Wiring Diagram Temperature Element Wiring The Badger Meter thermistors are not polarity sensitive. Connect the thermistor closest to the flow sensor to the Series 340N2 terminal block marked Temp 1 number 3 and number 2. The other thermistor wires to Series 340N2 terminal marked Temp 2 number 3 and number 2.
Programming the Badger® Series 340N2 Prior to introducing the Badger Series 340N2 onto a N2 network, it needs to be configured for the pipe’s size, desired units of measure, and its the default network address should be changed to an unused address to avoid any conflicts with other instruments on the N2 network. Programming the Series 340N2 is accomplished using the Badger Meter PC software. 1. 2. 3. 4.
Step 2 Select the desired temperature sensor units.
