Installation & Operation Manual
INTRODUCTION
The Data Industrial 340 BN/MB Btu Energy Transmitter from Badger Meter is an economical, compact device for hydronic
sub-metering applications. It uses an RS-485 connection for Modbus® and BACnet communication protocols and a solid state
switch for pulse output representing either flow or energy.
The 340 BN/MB Btu Energy Transmitter calculates thermal energy by integrating the liquid flow in a closed pipe system and
the differential temperature between the supply and return. The 340 BN/MB Btu Energy Transmitter requires one flow sensor
and two temperature sensors.
The temperature sensors can be two-wire 10k Ω Type II Thermistors or 100 or 1000 Ω RTDs that follow the IEC 751 curve.
The flow input may be provided by many of the Data Industrial line of flow sensors and other manufacturers' devices that
generate pulse or sine waves.
The onboard microprocessor and digital circuitry make precise measurements and produce accurate drift-free output. The
340 BN/MB Btu Energy Transmitter is programmed using the Badger Meter Windows® software and a Data Industrial Series
A301 programming cable. Calibration information for the flow sensor, units of measurement, communication protocol
settings and output scaling may be downloaded prior to installation or in the field.
The RS-485 Modbus settings include Baud Rate, Address and RTU/ASCII.
The RS-485 BACnet is an MS/TP slave device and includes Address, Baud Rate, Device Name, Device Instance Number and Max
Master Valve.
While the unit is connected to a PC or laptop computer, real-time flow rate, flow total, both temperature readings, energy rate
and energy total are available.
The 340 BN/MB Btu Energy Transmitter features three LEDs to indicate flow sensor activity, RS-485 activity and pulse output.
The 340 BN/MB Btu Energy Transmitter has an isolated solid state switch closure that is user programmed for units of energy
or flow. The output pulse width is adjustable from 10 ms to 5 sec.
The 340 BN/MB Btu Energy Transmitter operates on AC or DC power supplies ranging from 12 to 24 volts.
The compact cast epoxy body measures 3.65 x 2.95 inches (93 x 75 mm) and can be easily mounted on panels, DIN rails or
enclosures.
INSTALLATION
Mechanical Installation
The 340 BN/MB Btu Energy Transmitter may be surface mounted onto a panel, attached to DIN rails using adapter clips or wall
mounted using two optional enclosures.
Location
Although the 340 BN/MB Btu Energy Transmitter is encapsulated, all wiring connections are made to exposed terminals. The
unit should be protected from weather and moisture in accordance with electrical codes and standard trade practices.
In any mounting arrangement, the primary concerns are ease of wiring and attachment of the programming cable.
The unit generates very little heat so no consideration needs to be given to cooling or ventilation.

Wall Mounting
Optional metal and plastic enclosures are available to mount the 340 BN/MB Btu Energy Transmitter to a wall when no other
enclosure is used. The enclosure is first attached to the wall using fasteners through its mounting holes.
After wiring, the transmitter may be attached to the enclosure with the terminal headers facing in using the slots in the
mounting flanges. As an alternate mounting arrangement, the 340 BN/MB Btu Energy Transmitter may be fastened to the box
cover using double-sided adhesive tape.

DIN Rail Mounting
Optional clips snap onto the mounting flanges allowing the 340 BN/MB Btu Energy Transmitter to be attached to DIN 15, 32,
35 mm DIN rail systems.

Temperature Sensor Installation
Badger Meter offers several styles of 10k Ω Thermistors and 100 Ω Platinum RTDs in both direct immersion and Thermowells.
The style selected depends on system requirements and pipe size.
Direct Insert
Generally, direct insert sensors are used for smaller pipe sizes.
Figure 4: Direct Insert
Thermowell
Thermowells are recommended for larger pipes that are more difficult to drain for service.

Power Supply Wiring
The 340 BN/MB Btu Energy Transmitter requires 12-24 Volts AC or DC to operate. The power connections are made to the
ORANGE header. The connections are labeled beside the header. Observe the polarity shown on the label.
If a Badger Meter plug-in type power supply (Series 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 (–).

NOT:N Included with every 340 BN/MB Btu Energy Transmitter is a 340IK kit containing a screw, lock washer and nut to
connect the transmitter to earth ground. Connect the earth ground lug of the 340 BN/MB Btu Energy Transmitter to
a solid earth ground with as short a wire as possible. This will help prevent electrical interference from affecting the
transmitter’s normal operation.
