TRACER 1000 3G™LTT1-3G

GWR LEVEL TRANSMITTER

OPERATING INSTRUCTIONS

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.

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.

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.

(1)Interface mode is only available with the Interface communications option (see Part Numbers)

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.

PARAMETER DESCRIPTION OPTIONS

DK COMP Set dielectric of interface layer. This adjusts the velocity compensation for the

transmitted signal as it passes through the interface. Default 2.22 0-100

IFACE WIDTH

Set water reading (level 2) offset in the event of a merged echo. A merged echo

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

Adjustable

IFACE SIZE

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

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.
