INTRODUCTION
The Badger Meter Model 340BN Btu transmitter is an economi-
cal, compact device for sub-metering applications that utilizes the
BACnet
®
communications protocol.
The Model 340BN calculates thermal energy using the signal from
a flow sensor installed in a hydronic heating or chilled water sys-
tem, and signals from two 10 k
Ω temperature thermistors, 100Ω
RTD’s, or 1000
Ω RTD’s installed in the system’s inlet and outlet
points. The flow input may be provided by any Badger Meter
sensor and many other pulse or sine wave signal flow sensors.
The onboard microcontroller and digital circuitry make precise
measurements and produce accurate, drift-free outputs. The
Model 340BN is configured using Badger Meter Windows
®
based
programming software. Calibration information for the flow sen-
sor, units of measurement, and type of temperature sensor may
be preselected or entered in the field. Btu transmitter information
is available when connected to a PC or laptop computer. This
information includes flow rate, flow total, both T1 and T2 tem-
perature probe information, energy rate, and energy total.
The Model 340BN transmitter features two LED’s to verify BACnet
and flow sensor input activity.
The BACnet communications protocol allows the Model 340BN
transmitter to be assigned an address, and allow all measure-
ment parameters to be transmitted on a single 3-wire RS-485
bus.
The Model 340BN Btu transmitter operates on AC or DC power
supplies ranging from 12 to 24 volts.
The compact cast epoxy body measures 3.65”(93mm) x
2.95”(75mm) and can be easily mounted in panels, enclosures or
on DIN rails.
