Installation/Mounting
Handling and Mounting:
The Tracer 1000 generally comes supplied with a 3/4” MNPT process connection used for mounting.
The Tracer 1000 is mounted vertically at the top of the tank via the process connection thread. The threaded
process connection can be screwed directly into a standard female threaded tank connection. We recommend
using Teon tape on the process connection. Please ensure proper sealing of the sensor connection and take into
consideration temperature, pressure and other process conditions. The tank connection can be either anged
or non-anged, standard tank nozzle or pipe union. The Tracer 1000 should never be welded onto the tank
connections. Welding directly on the metal parts of the Tracer 1000 will cause serious damage to the transmitter
and void the warranty. The G tting thread of the Tracer 1000 is supplied with a gasket made of Klingersil C-4400,
thickness 0.0787”. The suggested tightening torque is 25 Nm (max. permissible torque is 45 Nm) with a max.
pressure of 580 PSIG.
Preparation:
FLO-CORP’s Tracer 1000 level transmitters are ready to install as-is, and are completely pre-congured per the
application data sheet or customer application information at time of order. The Tracer 1000 is shipped with a
calibration tag secured to the safety chain of the transmitter head. The calibration tag indicates the 4 mA equivalent
in level (usually 0.0”) and 20 mA equivalent in level (high level reading). If changes are to be made with this
conguration, please see section Operation and section Programming and Conguration.
Things to Avoid:
Avoid lifting or handling the Tracer 1000 by its probe; this can potentially damage the probe or the probe
connection. The Tracer 1000 should be handled by the hexagon connection or the lower section of the housing.
Avoid using the housing to screw the Tracer 1000 into the process connection. Use the hexagon tting to tighten
using a 1.25” wrench.
Avoid installing the Tracer 1000 probe so it is not directly impacted by liquids owing out of the lling inlet. This
may cause erroneous readings from the transmitter. If this situation is unavoidable, please consider the use of the
Coaxial Probe option.
Avoid installing the Tracer 1000 probe so it is touching or swaying towards other objects inside the tank, including

the tank nozzle. This may cause erroneous readings from the transmitter. Anchoring xtures are permissible and
supplied by the end-user. Please contact FLO-CORP for further details about using anchoring xtures.
Since the Tracer 1000 has an energy signature that is approximately a 1.5” to 2.0” radius from the center of the probe,
considerations should be made when engineering the proper probe location for mounting. If it is not possible to mount
the probe in a location that will be free of any objects that might interfere with the signal, than set-up conguration
changes can be made to possibly accommodate the mounting location (See Conguration Section).
Probe Selection
Probes for Liquids and Paste Applications:
The Tracer 1000 uses 1 of 2 possible probe congurations. The Rod probe is the most common. It can be used for
most liquids and is recommended for use with stilling wells and bypass chambers with a minimum inside diameter of
2.0”. The maximum length of the rod probe is 10 feet. The Rod probe is made of 316L Stainless Steel, 1/4” diameter.
The Rod probe can be ordered with an optional teon isolation sleeve and connections. Both congurations have a
threaded female connection on one end and bare end on the other. To install, thread the threaded connection into the
male threaded adapter on the Tracer 1000 transmitter.
The Coaxial probe is the second probe type available with the Tracer 1000. The Coaxial probe is typically used with
extremely low ∑r (dielectric) strength. It is also used if the agitation caused by inuent ow or mixing blades make the
level signal to erratic to read. The maximum length of the Coaxial probe is 10 feet. The Coaxial probe is made of 316
Stainless Steel, 1/2” diameter. To install, thread the threaded end of the inner rod into the threaded adapter of the Tracer
1000. Please make sure that the centering rod isolators are installed with approx. 20” space between each spacer.
The outer tube will now be ready
to slide over the inner rod, upward
towards the transmitter head. Next,
thread the threaded connection of
the outer tube into the upper hex
threaded connection. The Coaxial
probe assembly should now be
complete with the 3/4” male process
connection and is now ready to be
threaded into the 3/4” female tank
connection.

FLO-CORP assumes no responsibility for users incorrectly wiring their device. Please refer to the wiring diagrams and read all wiring
instructions for correct wiring of this device.
The Tracer 1000 is an active, single ended, non-isolated, 3 or 4 wire analog output transmitter. That is to say, the
common’s (or returns) for both the 24 volt DC AND the 4 - 20 mA output are tied together internally in the Tracer 1000
transmitter electronics. Therefore, when connected to a receiving device such as a PLC or multi-channel recorder,
please make sure to follow the devices connection instructions for single ended, non-isolated inputs. If in doubt, use an
input loop isolator to reduce ground loop problems.
Cable Entries & Shielding:
The Tracer 1000 enclosure has two 1/2” NPT cable entries that can be ordered with cable glands or sealed screw plugs.
In order to retain the IP-68 enclosure rating, both cable entries must be tted with IP-68 rated glands and/or screws and/
or conduit entry systems properly sealed. When wiring with shielded or armored cable, suitable cable glands must be
used. The contact between the metal housing and the shielding of the cable is made by using a suitable EMC type cable
gland. For proper signal/noise shielding, ground the cable shield on the transmitter side ONLY, not on the supply side.
Wiring:
First, verify that the power supply for the Tracer 1000 is switched off. Next, open the Tracer 1000 enclosure by turning
counterclockwise. It may be necessary to loosen the cover locking screw with a .15cm allen key. The grounding
screw on the transmitter housing should only be connected if there is complete assurance that the earth ground it will
be connected to is exactly equal to the ground potential of the transmitters power. If there is a ground offset you will
potentially experience faulty signal outputs. The grounding screw is not necessary to connect to earth ground for the
Tracer 1000 to work properly. Occasionally electrical codes will dictate the necessity for connection of the grounding
screw and again, in these cases make sure the ground potentials are equivalent. After pulling the cable into the housing
through the cable entry, install a drip loop outside the housing where the bottom of the loop is lower than the cable
entry of the housing. Using 16 to 22 AWG twisted shielded instrument wire, strip the wire ends carefully exposing each
conductor. The green terminals are screw-less, cage clamp terminals that only require a small at ended instrument
screwdriver to be simply pressed down on the orange lever. Insert the stripped end of the wire and release the
screwdriver from the lever; the wire is now connected. Follow the upper wiring decal by the terminals or follow the wiring
diagram on g. 4 (below)
Things to Avoid:
Avoid connecting the cable shielding on both ends. If you shield both ends of the instrument cable, you run the risk of
receiving electrical (RFI) or magnetic (EMI) noise or interference with the measuring signal.
Avoid conduit system leaks or joints or connections that will allow water to enter into the transmitter housing. Any amount
of water that will enter the housing will damage the electronics and will induce failure to the system.
Avoid using cable end sleeves on the terminations of the instrument cable. The cage clamp terminals work best with
bare conductors.

is a PC software based tool that allows the user to congure basic and advanced settings, diagnose and troubleshoot
as well as save settings in a .CSV format. The Tracer Conguration Tool communicates to the PC via factory supplied
HART® Modem. The Modem is connected to the USB port of the PC and the opposite end is connected with alligator
clips to a factory supplied 250 Ω resister (please refer to the Tracer Conguration Tool information in the Appendix). 2.)
Basic conguration changes can also be made from the interface on the transmitter electronics. Please see g. 5; the
DIP switch, a single push button and a LED for visual feedback are used for all settings. All settings required to get
the Tracer 1000/2000 fully operational can be performed directly from the transmitter electronics. The DIP switch has 8
small white levers. Small numbers from 1 to 8 are printed underneath the levers. The DIP switches must be turned on
in the proper sequence starting with DIP switch position 8 and move towards position 1. There is also a color code for
these levers. DIP position 8 is red, DIP position 5,6,7 is blue, and 1,2,3,4 is gray. The upper position of the lever is off/0
and the lower position of the lever is on/1.
The color code on the DIP switches correspond to the color code on the switch settings guide in g. 5.
RED: indicates the DIP switch position 8 which switches between measuring and conguration mode. When DIP switch
8 is on/1. the Tracer 1000/2000 can be congured. When entering into the conguration mode, the LED will change
state to blinking alternately green and red. When switching DIP switch 8 back to off/0, the LED will switch back to
blinking green ONLY.
BLUE: Indicates the DIP switch positions through which groups of functions are selected. example: all functions related
to the analog current output or the switching output.
GRAY: Indicates the DIP switch positions through which individual functions/congurations are selected.
Push button and LED: After setting all DIP switch positions to represent the desired function you would like to program
(as described in g. 6), press the push button to execute the desired function. Execution of the function is indicated by
the LED remaining green until the function has been properly executed. Upon execution the LED returns to blinking
alternately green and red. The only exception to this push button sequence is for function group 4 (reset to the factory
conguration the unit was received in) and function group 5 (measure probe length). For these function groups the push
button must be pressed and held for a minimum of 10 seconds for the functions to be executed.
Programming and Conguration
Conguration of the Rod Probe or Wire
Cable Probe:
FLO-CORP’s Tracer 1000 level transmitters
are ready to install as-is, and are completely
pre-congured per the application data sheet
or customer application information at time
of order. The Tracer 1000 is shipped with a
calibration tag secured to the safety chain
of the transmitter head. The calibration tag
indicates the 4 mA equivalent in level (usually
0.0”) and 20 mA equivalent in level (high level
reading). If changes are to be made with
this conguration, the following steps can be
programmed. For most standard applications,
execution the three basic conguration steps
will be sufcient to achieve a fully functional
sensor.
1. Perform a Disturbance Signal Scan:
The disturbance signal scan is a powerful
disturbance signal suppression feature. The
Tracer 1000 scans its entire probe length for
any disturbance signals in the application that
could potentially be misinterpreted as a level

reading.
The disturbance is memorized and suppressed during operation so only the actual level signals caused by the material
level are measured. The disturbance signal scan works most effectively on stationary objects like a latter, pipes, tall and
thin nozzles, chains or other objects that are in close proximity to the probe. The Tracer 1000 must be installed in the
tank or silo to execute a disturbance signal scan and the tank or silo must be empty or near empty. Set the following DIP
switches to the ON/1 position. 8 - 7 - 6 - 4 All other switches should be in the off position. The LED will blink alternately
green and red. Press the push button. The LED will remain green for a few seconds while the disturbance signal scan is
being performed.
Once the scan is completed successfully, the LED will return to blinking alternately green and red. If this is the only
function you want to perform, set the following DIP switches to the OFF/0 position. Otherwise, continue to the next basic
step:
2. Setting the Lower Range Value (4 mA): Please see g. 7
Fill or empty the material in the tank to the level of the tank where you want the 4mA measuring range to be. It is
recommended that the level stays within the measuring range indicated by the (M) in g. 11. Set the following DIP
switches to the ON/1 position. 8 - 7 - 4 All other switches should be in the off position. The LED will blink alternately
green and red. Press the push button. The LED will remain green for a few seconds while the lower range signal value
is being performed. Once the scan is completed successfully, the LED will return to blinking alternately green and red.

If this is the only function you want to perform, set the following DIP switches to the OFF/0 position. Otherwise,
continue to the next basic step:
Setting the Upper Range Value (20 mA): Please see g. 8
Fill or empty the material in the tank to the level of the tank where you want the 20 mA measuring range to be. It is
required that the level stays within the measuring range indicated by the (M) in g. 14. Set the following DIP switches
to the ON/1 position. 8 - 7 - 3 All other switches should be in the off position. The LED will blink alternately green and
red. Press the push button. The LED will remain green for a few seconds while the upper range signal value is being
performed. Once the scan is completed successfully, the LED will return to blinking alternately green and red. If this is
the only function you want to perform, set all of the DIP switches to the OFF/0 position. Once the DIP switches are set to
the off position, the LED will change to blinking green indicating the transmitter is in the RUN or Operating mode.
NOTE: The factory default for the analog output settings are Lower Range Value setting at 4 mA and the Upper Range
Value setting at 20 mA. It is possible however to reverse these settings. If the user desires to have the 4 mA setting
represent the high tank value and the 20 mA setting represent the low tank value. Please follow the instructions below
for programming of these settings.
3. Setting the Switching Output (Active PNP -
Normally Closed is Factory Default)
The switch can be set to activate or change
state at a single point or it can be set to
activate or change state at one point (lower
threshold), and then activate or change state
at another point (upper threshold).
First, we will describe setting the switch to
activate or change state at a single point: Fill
or empty the material in the tank to the level of
the tank where you want the switch point to be
activated.
Next, set the following DIP switch to the ON/1 position. 8 - 6 - 3 All other switches should be in the off position. The LED
will blink alternately green and red. Press the push button. Once the set-point adjustment is completed successfully,
the LED will return to blinking alternately green and red.
Next, set the following DIP switch to the ON/1 position. 8 - 6 - 4 - 3 All other switches should be in the off position.
The LED will blink alternately green and red. Press the push button. Once the set-point adjustment is completed
successfully, the LED will return to blinking alternately green and red. Now the switching output will be set to activate of
change state at this single point of tank level. Every time this level point is reached the switch will change state.
Now we will describe setting the switch to
activate or change state at one level of the
tank, hold that state until another level in the
tank is reached. Fill or empty the material
in the tank to the level of the tank where
you want the switch point to be activated.
(Example: 80% ll level)
Next, set the following DIP switch to the ON/1 position. 8 - 6 - 4 - 3 All other switches should be in the off position.
The LED will blink alternately green and red. Press the push button. Once the set-point adjustment is completed
successfully, the LED will return to blinking alternately green and red. Fill or empty the material in the tank to the level of
the tank where you want the switch point to be activated. (Example: 20% ll level)
Next, set the following DIP switch to the ON/1 position. 8 - 6 - 3 All other switches should be in the off position. The LED
will blink alternately green and red. Press the push button. Once the set-point adjustment is completed successfully,
the LED will return to blinking alternately green and red.
Reminder: When nished with programming and returning to RUN mode, switch all switches to the OFF/0 position by
switching the least position and moving towards the switch 8 position.

When programming or changing the conguration of the Coaxial probe, the only values needed to be changed should be the
Lower Range Value and the Upper Range
Value, switch settings and response time.
See programming steps 2 & 3 for setting these
values.
Please remember to tighten the housing cover
properly by turning it clockwise.
Things to Avoid:
Avoid reversing the sequence when setting the DIP switches to the ON/1 position or when switching them back to OFF/0
position. The DIP switches should always be turned on from the 8th position rst to the least position last. Alternately, when
setting the DIP switches to the off position, they should always be turned off from the least position rst and the 8th position last.
Avoid cycling power while performing the programming steps. If power is interrupted in mid-programming mode, with power
off return all DIP switches to the OFF/0 position and apply power. Then, start process from the beginning of the step that was
interrupted.
Avoid lifting the DIP switch levers with pliers. Using a small at instrument screwdriver or at object will decrease the chances
of lifting the lever off of the switch foundation.
Probe Length, Dead Band and Measuring Range
Probe Length:
The upper or top reference point for denition of the probe length (L) is always the sealing surface of the connection thread.
The probe length is an important mechanical dimension which is needed to make sure the probe physically ts into the tank at
the anticipated mounting location. The probe can touch the bottom of the tank, but it is not necessary. The actual measuring
range (M) of the Tracer 1000 is not the probe length (L). The measuring range of the Tracer 1000 is the total probe length less
the upper dead band (D1). The dead band is a small inactive area at the top (D1) of the probe. These are due to the presence
of unavoidable signal disturbances at the top of the probe. In the top dead band the measurements are non-linear or have
reduced accuracy. Therefore, it is not practical to actually measure level within those inactive or dead band area. The length
of the dead band depends on the probe type and the ∑r (dielectric) strength of the material being measured.
Restore Defaults
Set the following DIP switches to the ON/1 position. 8 - 5 - 4 All other switches should be in the off position. The LED will
blink alternately green and red. Press the push button. The LED will remain green for a few seconds while the reset to factory
conguration is being performed.
Once the conguration
is completed
successfully, the LED will return to blinking alternately green and red. If this is the only function you want to perform, set all of
the DIP switches to the OFF/0 position. Once the DIP switches are set to the off position, the LED will change to blinking green
indicating the transmitter is in the RUN or Operating mode.
