Data Acquisition
System (DAS)

Badger Meter is a leading supplier of
ow meters and related equipment.
Established in 1905, Badger Meter
has continued to innovate ow
measurement solutions that provide
benets in many applications.
Accurately measuring ow and
other instrument data is the rst part
of obtaining information from an
application. Collecting and managing
that information is the next part.

Instrument data has been collected
in a variety of manners. Observing
a local display has been a traditional
method and remains popular today.
Connecting output from a sensor to a
data management system on a pulse,
analog, or bus communication line is
also widely used. In the recent past,
wireless technology has allowed for
remote connectivity without the need
for wires. This of course simplies the
installation of each device.

No matter your choice of how data is
gathered, either wired or wireless, the
data needs to be stored and managed
so it can be used. Dataloggers,
databases, and other data storage
methods are all found in applications
around world. Many of these systems
require custom software and hardware
and use closed protocol systems
that lock a user into that
specic infrastructure.

Gathered data can then be used to
benet the user by demonstrating
instrument conditions at the times that
the data was collected. This is what
many users are trying to accomplish
in the most simple and cost eective
manner possible. This is where the
Data Acquisition System (DAS) from
Badger Meter comes in by oering
these and many more features.

What is it?

The Badger Meter Model 3700 is a TCP/IP based DAS that
allows for simple setup and conguration. Simply connect
an Ethernet cable and use standard browser software to
connect and congure the unit. The Model 3700 also uses a
standard modbus input. Data exchange on this protocol on
wired devices or through the Model R9120-5 modbus mesh
network transceiver greatly expands the number of inputs
that can be acquired.

How does it work?

Like other technologies, the Model 3700 DAS records input
data into a log le that a user can view when needed. The
eight dynamic inputs can receive a variety of instrument
connections. These can be pulse, resistance, current or
voltage. The modbus input allows for up to 249 additional
channel inputs. These could be used for expansion of pulse
and analog inputs or for adding a variety of modbus
based devices.

What is the Model R9120-5 and how
does it work?

The Badger Meter Model R9120-5 is a modbus based
transceiver. When more than one of these units are used, it
creates a self-healing mesh network. This network can be
connected directly to the Model 3700 via the modbus input.
Each Model R9120-5 allows for two pulse inputs and a
modbus input. These transceivers create a wireless network
that benets many applications by simplifying installation
and reduces cost, while adding a large number of device
inputs and oering easy expandability for the future.

What is the Model 350T?

The Badger Meter Model 350T is a short hop Radio
Frequency (RF) transmitter that can connect to many scaled
pulse outputs. The 350T is a battery powered unit
which allows for remote connectivity. The Model 350R is
the receiving end of the 350T. This can be installed with a
Model R9120-5 or a Model 3700 and add data into
the network.

What if I need more inputs?

The A8911-23 is an I/O expansion module that is modbus
based. It allows for four additional pulse inputs and four
analog inputs. This device can be added on the modbus
network either at the Badger Meter Model 3700 or at any
Badger Meter Model R9120-5 . Additionally, the HD pulse
input allows for 23 pulse inputs on one Modbus address.

Put it all together

Using the Model 3700 by itself or with multiple Model
R9120-5 units and/or with multiple modules creates a data
acquisition system that is both highly functional and simple
to use and maintain. Adding devices can be done quickly
for future expansion. The user can plug the Model 3700 into
a LAN and collect the data from literally anywhere in
the world.
