Introduction

Please read carefully! No liability can be accepted for damage caused by improper use or installation of the Tracer 3000 Level Transmitter.

The Tracer 1000™ 3G Guided Wave Radar Level Transmitter is ideal for level measurement of liquids, solids, bulk
materials, sludge, powders and granules to a distance of 60ft 8 in. Guided-wave technology sends the radar pulse down

a probe to measure either liquids or solids. The pulse hits the surface and is reected back up the probe to the sensor,
where the transit time is translated into a distance using time of ght and time expansion. The amplitude of the reection

depends on the dielectric constant of the product. This technology is not affected by pressure, temperature, viscosity,
vacuum, foam, dust, changes in dielectric constant or coating of the probe.

Safety Precautions

If you are unsure of the suitability of a Tracer 1000™ for your installation, please consult your FLO-CORP representative for
further information.

NOTE: REMOVE ALL PACKING INSERTS BEFORE OPERATING LEVEL TRANSMITTER.

Authorized Personnel

All operations described in this operating instructions manual must be carried out only by trained specialist personnel

authorized by the plant operator. During work on and with the device the required personal protection equipment must
always be worn.

Warning about misuse

Inappropriate or incorrect use of the instrument can give rise to application-specic hazards, e.g. vessel over ll or damage

to system components through incorrect mounting or adjustment.

General Safety Instructions

The user must take note of the safety instructions in this operating instructions manual , the country specic installation

standards as well as all prevailing safety regulations and accident prevention rules. The instrument must only be operated

in a technically awless and reliable condition. The operator is responsible for trouble-free operation of the instrument.

During the entire duration of use, the user is obliged to determine the compliance of the required occupational safety
measures with the current valid rules and regulations and also take note of new regulations.

TECHNOLOGY

The Tracer 1000™ 3G uses TDR Technology: low-energy, high-frequency electromagnetic impulses, generated by the
sensor’s circuitry, are propagated along the probe which is submerged in the liquid or solid to be measured. When these

impulses hit the surface of the media, part of the impulse energy is reected back up the probe to the circuitry which then
calculates the level from the time difference between the impulses sent and the impulses reected. The sensor can output
the analyzed level as a continuous measurement reading through its analog output. TDR Sensors are also known as Guided

Radars or Guided Wave Radars.

DIGITIZE FUNCTION

The ‘Digitize’ function is an automatic setup routine to create a digital map of false echoes generated by
problems such as non-recommended mounting.

The function should be performed after physical installation to the application.

During the process the unit will prompt a measured distance (this must be either the material level if material
is touching the probe, or end of probe of the vessel is empty. For Interface model type it must be the Upper
Layer). The distance is adjustable if the displayed distance is not correct.

Ensure the value is not greater than the distance to the material level.

For best results follow this routine:

1) Ensure the unit is mounted according to mounting specications and requirements.

2) Ensure the material to be measured is in contact with the actively measured part of the probe.

3) Select Dielectric pre-set value of most similar to material to be measured. For Interface model type it must
be the Upper Layer).

4) Run Digitize routine. Conrm displayed distance is either material level.

INTERFACE MODE SETUP

Interface mode is only avaialble with the Interface communications option (see Part Numbers).

The Interface mode is designed to measure applications with low to high dielectric constant layers.

The transmited signal relfects off the Upper Layer and continues through the Interface and reects from the

Lower Layer.

The unit provides a level reading for both the Upper and Lower Layers available via HART. The Lower Layer
will always be transmitted to the 4-20mA output.

When Interface mode is Enabled, the following parameters are adjustable.

DK COMP

transmitted signal as it passes through the interface. Default 2.22

will occur if the interface is too thin to produce a separate echo. The offset is
measured from the end of the merged echo backwards. Default 150mm (0.5ft)
Note: This is an advanced setting and should not be adjusted without expert
knowledge

Sets the echo size (in signal voltage) to dictate whether an echo is from the
Interface or Level. If the echo is larger than the value the unit will assume no
Interface is present and will set Level 1 reading to be the same as Level 2 reading.
If the echo is smaller it will assume there is only an Interface layer measurable and
will set Level 2 to end of probe measurement. Default 2.34
Note: This is an advanced setting and should not be adjusted without expert
knowledge

High and Low level distances can be programmed manually or you can run
Autoset. Autoset can be used to program the High or Low level based on the
material level which is touching the probe when the function is run.

Tracking speeds can be set to Fast, Medium, Slow and Custom (measured in
Displayed Units per hour)

Choose closest Dielectric range of Upper material Level from the pre-set list.
Select lower value if unsure. <2 will be appropriate for most Interface applications.

Confirm displayed distance is either material level (for Interface applications
it must be the Upper Layer) or end of probe if vessel is empty.
Ensure the value is not greater than the distance to the material level.
See ‘Digitize Function’ for additional critical information.

Program Dielectric value of Upper Material Layer in Interface Menu

Increasing Damping value if a smoother response trend is required. This
value is automatically set by the Tracking speed.

Wiring in Hazardous Locations

Mounting - Instruction for Rotating the Housing

• There are specic rotation points which should be used while mounting the unit into place.

• The Housing Compartment should never be used to rotate the device during mounting.

• For rotating the housing after installation see 'Rotating the Enclosure' section.

When Installing the Tracer 3000 unit, use spanner or

wrench ONLY at Process Fitting as indicated.

Placement Requirements

Nozzle / Socket Mounting

Stand Pipe / Flanged Mounting

Mounting - Conductive Vessel

Unit performance is most optimized when there is a ground reference between the mounting
(metal ange or thread) and the vessel. Metallic or metal reinforced vessels are ideal.

Mounting - Non Conductive Vessel

A non conductive vessel will require a conductive metal strip or equivalent connected to the

metal ange or thread and running along side the vessel for at least the Probe insertion length.
A conductive metal sheet (min 0.5m (8") should also be mounted on the roof and be in contact
with metal thread or ange. If a seal / gasket is used between the ange and the vessel ensure
non coated / painted bolts are used to create ground reference with vessel.

Gland Entry Wiring

Adjusting Probe Length

Rigid Probes

Cut rigid probes to appropriate length. After adjustment, you must change the 'ProbeLength' Parameter in 'Advanced'

menu to represent the new length (password 222).

Flexible Probes

(a) Mark the point at which the exible cable enters the cable weight.
(b) Release the cable weight grub screws with hex key.
(c) Measure and note the length of cable concealed within cable weight.
(d) Cut cable noting the length of cable must include the concealed length above.
(e) Re-insert the cable into the weight and tighten grub screws to tightening Torque of 20Nm. Use loctite 243 or

equivalent on grub screws to secure once completed.

(f) Adjust ProbeCalibr Parameter in 'Advanced' menu to represent new length (password 222).

Rotating Ex Rated Enclosures

The Ex d gland which couples the sensing probe to the ameproof enclosure provides a critical sealing

function for the enclosure. Internal wires are passed through this gland and the high integrity seal. This
gland

incorporates a Union Joint which is designed to rotate.
However, this rotation is limited to one-time adjustment of Display orientation after installation on site.
ONLY one 36mm spanner applied to the Hex of Union Joint to rotate enclosure to desired orientation as
allowed. DO NOT hold the enclosure during this procedure.

Rotation beyond these strict limits can damage the internal cables
Ensure Enclosure follows the spanner rotation and assembly integrity is not compromised
