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 Teon 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-congured 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

conguration, please see section Operation and section Programming and Conguration.

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 conguration

changes can be made to possibly accommodate the mounting location (See Conguration Section).

Probe Selection

Probes for Liquids and Paste Applications:

The Tracer 1000 uses 1 of 2 possible probe congurations. 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 teon isolation sleeve and connections. Both congurations 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 inuent 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.
