Tracer®VM Bluetooth Interface
Model number VMBTI-102
Operating Instructions
General
The TracerVM Bluetooth Interface collects, transmits and saves data from
TracerVM Base Flowmeters installed in injection mold cooling circuits.
Flowmeters purchased separately are connected via cable to the TracerVM
Bluetooth Interface. The Interface provides power to each owmeter and
receives voltage signals for temperature and ow.
The TracerVM Bluetooth Interface wirelessly transmits ow and
temperature for display on a tablet or smartphone. Files can be created
using the free app and saved on USB ash drive connected to the Interface.
The Interface also communicates over Ethernet connection to PC software
for network le storage and alerts. The les are easily read into database
management software for reference or analysis.
When used with PC software, a dry contact switch is available for
connection to a peripheral or machine control to signal an alarm for out of
limit cooling water conditions.
App software is available for download at no cost from Google™ Play or
iTunes™ stores and is required to view data. Search for “Tracervm” to
locate.
PC Based software is provided free of charge from Burger & Brown
Engineering, Inc. It is available for download at this web address: www.

Power
Attach the power cable to the P1 connector according to the chart below.
Individual wires are 24AWG stranded copper. Attach 8 to 28VDC power to
the unit for correct operation. Do not energize the circuit without TracerVM
Base units connected.
Power supply other than 8 to 28VDC may damage the electronics!
Ensure that power supply provides Earth Ground (0V) and
not a reference. Earth Ground is required for reliable ow and
temperature output display.
EMI/RFI Interference
Care should be taken to route power and signal cable
away from motors and pumps. Signal integrity may be
adversely aected by close proximity of the wiring to
machinery producing high frequency emissions.
Cables to TracerVM
Maximum eective signal cable length is 2.9m (10ft)
as supplied. Splicing extra length to the cable is not
recommended. Sensor cables are supplied with the
TracerVM Base units.
Flow and Mounting Direction
Orient the TracerVM Base units so the ow direction
of the process uid matches the directional arrow on
the body of each meter. Flow in the opposite direction
of the arrow will yield inaccurate voltage output. The
presence of air bubbles in the process uid will also
create an inaccurate voltage output. Refer to TracerVM
Base Instructions (Form 187) for details.

Network Connection Requirement
When used with PC Software, the TracerVM Bluetooth Interface must be
connected through a DHCP Client such as a wireless router or Local Area
Network that will automatically assign an IP address. The Interface will
not communicate if plugged directly into a computer.

Installation
TracerVM Bluetooth Interface must be wired to TracerVM Base units to transmit ow and
temperature values from the process. Begin by installing TracerVM Base units into the ow
path (see Form 187 for installation details) except for wire terminations.
Mount the Bluetooth Interface box in a dry location. Occasional water spray will not permeate
the electronics housing if correct installation practices are used. See Figure 1 for mounting
hole locations. Use #8 screws to mount the housing.
Remove 6 cover screws and the interface cover to expose the circuit board inside the box.
Connect Power Cable
Loosen the Power Cable nut on the side of the box. Insert the cable through the cord grip with
approximately 8cm (3") of loose cable on the inside of the box. Tighten the cord grip nut on
the outside of the box hand-tight. Locate P1 connector on the left side of the circuit board (See
Figure 2). Hold down the small button on the top of the connector and insert the red and black
wires of the power cord according to Figure 3: PWR = Red Wire, GND = Black Wire.
Connect Dry Contact Switch (optional)
Connect switch leads from external device for alarm state notication to Dry Contact Switch
Connector on the circuit board. Loosen the Dry Contact nut on the side of the box. Insert the
cable through the cord grip with approximately 8cm (3") of loose cable on the inside of the
box. Tighten the cord grip nut on the outside of the box hand-tight. Locate P14 connector on
the left side of the circuit board (See Figure 2). Strip and insert the wires (20 - 26 AWG) into
the connector according to Figure 4: Normally Closed, Common, Normally Open.
Connect the TracerVM Base Units
Eight connectors on the circuit board accommodate external TracerVM Base units. Each
TracerVM Base unit must be wired to a connector on the Bluetooth Interface circuit board. See
chart at right for Cooling Circuit Number and Corresponding Connector Number. See also
Figure 2 on page 2.
Prepare wire ends. Cut cylindrical connector end o of TracerVM Base cable if present. Cut
away 25mm (1") of external cable jacket. Use caution not to damage wire insulation. Strip
inside wire ends to expose approx. 6mm (1/4") of copper wire. Twist copper wire together so it
will insert easily into the connectors on the circuit board.
Loosen the nut on a TracerVM cord grip in the top of the box. Insert the TracerVM Base
cable through the cord grip with approximately 5 cm (2") of loose cable on the inside of the
box. Tighten the cord grip nut on the outside of the box hand-tight. Locate the appropriate
connector along the edge of the circuit board. Hold down the small button on the top of the
connector and insert the color-coded wires of the cable according to Figure 5 (left to right:
brown, white, yellow, green).
Ensure that any unused cord grips have a short length of unattached wire installed in them to
maintain the liquid-resistant properties of the enclosure. Secure each cord grip hand-tight.
Set the Corresponding DIP Switches
Each connector is associated with a DIP (Dual In-Line Package) Switch below it. Flow range
must be matched to the sensor on the TracerVM in order for values to be correctly displayed on
the mobile app and PC. Set the switches according to the chart below. See Figure 6. Position 3
should always be set to "OFF".

The Smartow Data Logger collects and displays temperature
and ow rate information from TracerVM Bluetooth Interface
Modules. The information is saved to a .csv le that can be
imported into a database or spreadsheet for future analysis or
process reference. Medical molding applications or other critical
molded parts that require process verication or traceability will
benet from this technology.
The Data Logger can collect from up to 10 Bluetooth Interfaces
at once. Each Bluetooth Interface connects up to 8 owmeters
for a maximum of 80 cooling water lines. One .csv le is created
for each Interface. Files are only comma delimited.
The software is provided as a .zip le. Extract the installation
program and install onto a computer in the default location or
select a folder according to your preference. Executable le name
is "SmartFlow Data Logger.msi".
There are two viewing screens: "Home View" and "Session View".
Home View: Metric or English Units and Interface Modules are
selected. A graph of the ow rate and temperature is available
for each Interface. The user selects the area on the screen for
each Interface from the list of those available.
Session View: Session options and le output are congured.
Selectable options are:
• Manual or Scheduled Duration
• Session Name
• Sensor Names
• Log Rate in seconds
• Enable or Disable Alarms and Audible Indication
• Metric or English Units
• Graph View
• Output File Name (*.csv extension)
Conguration Files: Data Logger Conguration les (*.bnb
extension) store program settings to save time and maintain data
consistency. When starting up or exiting the Data Logger, a pop
up window will prompt for le name to be saved or loaded.
A Conguration le can only be loaded before a session is started.
Conguration les may be saved at any time using the buttons
in the "Session Setup" section (upper left) of the Data Logger
Display. Parameters that can be saved are:
• Alarms settings
• Session/Sensor Names
• Units
• Log Rate
• Audible Alarm Enable

Start the Smartow Data Logger Application. Check that each
TracerVM Bluetooth Interface is connected to 8 to 28 Volts DC
power supply with earth ground and connected to the local
network.
1. Highlight the "Home View" box. Select your preferred units
(English or Metric). Changing units after a session is started
will clear all data without saving.
2. Select the name of a TracerVM Bluetooth Interface from the
list at the top of the screen. Select the area of the home view
screen for individual interface display. Once an interface is
assigned to the home view, the name in the list will change
from yellow to green. Note: There are up to 10 possible
graph locations on the "Home View" screen. The number
of locations you can select is determined by the number of
Interfaces connected to the local network. If one Interface is
connected, there will only be one available graph location.
3. To start a logging session, the Interface must be assigned
in the "Home View" with visible graph (steps 1 & 2). Select
the "Session View" box. Select the Interface from the list
of available modules in the top window. Then select "New
Session".
4. Once a session has been started, you can start either a Man-
ual Session or a Scheduled Session.
5. Once a session has been opened, the software begins record-
ing data that can be saved by starting a "Manual Session".
This rolling history is gathered for up to 72 hours without a
session being actively recorded. This is available as long as
a session is open and the program is running. Note: If units
are changed on a session view, the rolling history will be
cleared.
6. The session name, as well as the names of each sensor can
be changed by clicking the Session/Sensor names button.
7. Log Rate is the rate at which data is collected in terms of
seconds between data points. The value can be set from 1
second up to 3600 seconds (1 hour).
