Page 5: Introduction
The temperature sensors can be two-wire 10 kΩ Type II Thermistors or 100 or 1000 Ohm RTDs that follow the IEC 751 curve. The flow input may be provided by many of the Badger Meter line of flow sensors and other manufacturers' devices that generate pulses or sine waves. -
Page 6: Surface Mount Installation
Series 340 BN/MB Transmitter Surface Mount Installation The Series 340 BN/MB may be mounted to the surface of any panel using double sided adhesive tape or by attaching fasteners through the holes in the mounting flanges of the unit. 1.60” (40.6mm) 3.65”... -
Page 7: Din Rail Mounting
Figure 3: Din Rail Mounting Temperature Sensor Installation Badger offers several styles of 10k Thermistors and 100 Ohm Platinum RTDs in both direct immersion and Thermowells. The style selected depends on system requirements and pipe size. Direct Insert Generally for smaller pipe sizes direct insert sensors are used. -
Page 8: Hot Tap
For pipes that cannot be drained even for initial installation, we offer a Hot Tap version. Model THT – available as 10k Thermistor version only. Figure 6: Hot Tap Electrical Installation All connections to the Badger® Series 340 BN/MB are made to screw terminals on removable headers. Wire 3/32" Flathead Screwdriver... -
Page 9: Power Supply Wiring
Observe the polarity shown on the label. If a Badger Meter plug-in type power supply (Model A-1026 or A-503) is used, connect the black/white striped wire to the terminal marked positive (+) and the black wire to the terminal marked negative (-). -
Page 10: Sensor Wiring
The 340BN/MB is very versatile, and can accept both Pulse and Zero Crossing Sine Wave flow sensors. Excitation voltage is also provided for Three Wire Powered Sensors (Example: Hall Effect, of Badger 4000 Series). See the Programming Section for configuration instructions. -
Page 11: Thermistors
Pulse Output Wiring The Badger Meter Series 340 BN/MB has solid state switch output rated for a maximum sinking current of 100 mA @ 36V DC. In most cases the pulse out (+) terminal of the Series 340 BN/MB will connect to the input pulse (+) and the pulse out (-) terminal to the input pulse (-) of the receiving device. -

Page 13: Communications Cable Wiring
USB to COM Port adapters can be used if the DB9 COM port is not available. NOTE: The Badger Meter A301 Cable will work with all Series 300 products. However the older version of the cable (A300) does not have sufficient bandwidth to work with the Series 340 BN/MB Transmitters. -

“D.I.C. COM port”, taking care to properly align the tab on the plug and socket to maintain polarity. Connect the DB9 connector of the Badger Meter Model A301 communications cable to a PC COM port that has the 340 software installed. - Page 15 Installation & Operation Manual Once the 340BN/MB has been selected the appropriate COM port can be selected from the Configuration Tab. Figure 17: Select Set COM Port Figure 18: Select the COM Port If the COM and Device type have been properly selected, the “---” will be replaced with values. If this does not occur, communication has not been established, and you cannot continue to the next step.
- Page 16 Series 340 BN/MB Transmitter If communication still does not occur, and you are using a DB9 to COM 1 or COM2, try using a USB to COM adapter. This will usually create a new COM port that was not previously listed. Windows Device Manager can be helpful in determining the actual COM ports that are available.

Page 18: Flow Sensor Section
Flow Sensor Section Figure 23: Pulse or Sine For most Badger Meter sensors the sensor type is “Pulse”, and the “K” and “Offset” values can be found in the respective Flow Sensor Manual. “Sine” is used for zero-crossing flow sensors (some turbine meters, etc.) Several flow rate and flow total units of measure can be selected from the pull-down menu. -
Page 19: Energy Calculation
Installation & Operation Manual The “Zero Temp Diff” is a very powerful feature in this product which allows any inaccuracies of drift in the temperature sensors, or 340 temperature measurements to be cancelled out. This correction can be either manually typed in or if the temperature sensors are known to be at exactly the same temperature, the “Zero Temp Diff”... -

Page 24: Rs-485 Network Test
Although it uses Modbus settings, it is RS-485 communication it is testing. The test requires connection to a COM port using the Badger Meter A302-20 RS 485 to RS-232 convertor cable. This cable can also be helpful with other diagnostics programs and devices that use an RS-232 port to communicate. -
