Installation on a Tank with a SAE J1810 5-Bolt Fitting and Focus Tube

If a focus tube is used for a tank with sensor mounting hole and use a saw a SAE J1810 5-bolt fitting, determine the depth of the tank at the location of the tank

with a metal-cutting blade to trim the focus tube so that it reaches 1” (2.54cm) above the tank bottom when mounted. Remove any burrs from the end of the focus

tube after trimming. Optionally, install the focus tube cap (see below).

Next, place the gasket included with the focus tube over the focus tube (between the focus tube flange and the tank mounting flange), and then drop the focus

tube into the hole so that the bolt holes on the focus tube, focus tube gasket, and tank fitting all line up (WARNING – the gasket must be properly aligned; it only

fits one way).

Place the gasket included with the TLM100/TLM150 over the focus tube so that the bolt holes line up (WARNING – the gasket must be properly aligned; it only fits

one way), then place the TLM100/TLM150 sensor component on top of the TLM100/TLM150 gasket so that the bolt holes line up.

Insert mounting screws into the bolt holes on the TLM100/TLM150 sensor component, and thread them into the tank fitting (the tank fitting may instead have studs

installed, so in this case, install the nuts over the studs), tightening them to a torque of 10-15 in-lbs (1.1-1.7 N·m). Do not use threadlocking compounds containing

methacrylate ester, such as Loctite Red (271), as they will cause stress cracking of the plastic enclosure.

Fitting

If a focus tube is used for a tank with sensor mounting hole and use a saw a SAE J1810 5-bolt fitting, determine the depth of the tank at the location of the tank

with a metal-cutting blade to trim the focus tube so that it reaches 1” above the tank bottom when mounted. Remove any burrs from the end of the focus tube after

trimming. Optionally, install the focus tube cap (see below).

For a threaded tank sender mounting hole, first thread the adapter into the tank opening and tighten to a torque of 3-5 ft-lbs (4.1-6.8 N·m).

Next, place the TLM100/TLM150 gasket over the adapter so that the bolt holes on the gasket line up with the bolt holes on the adapter (WARNING – the gasket

must be properly aligned; it only fits one way). Place the TLM1 t holes on the TLM100/TLM150 00/TLM150 sensor component on top of the adapter so that the bol

sensor component line up with the bolt holes on the adapter.

Place the included mounting screws through the bolt holes on the TLM100/TLM150 sensor component, and thread them into the adapter, tightening them to a

torque of 10-15 in-lbs (1.1-1.7 N·m). Do not use threadlocking compounds containing methacrylate ester, such as Loctite Red (271), as they will cause stress

cracking of the plastic enclosure.

Installation of the Focus Tube Cap (Optional)

The focus tube cap may be installed over the end of a focus tube that is used with a Maretron TLM100/TLM150 ultrasonic tank level monitor. Use the focus tube

cap if the tank bottom is not flat below the location of the focus tube to ensure that the ultrasonic signal is reflected back to the TLM100/TLM150 when the tank is

empty.

Note that when the fluid is below the level of the focus tube cap, the ultrasonic signals will be reflected by the focus tube cap and not the liquid surface, and so the

reported tank level will not reflect the actual tank level.

Please follow these instructions to install the focus tube cap onto a focus tube.

1. Cut the focus tube to length as described above.

2. Test-fit the focus tube cap on the end of the focus tube and ensure that it can completely slide onto the focus tube. You may need to use a rubber mallet to

completely seat the focus tube cap.

3. Mix the epoxy according to the instructions on the epoxy packet using the included wooden mixing stick.

4. Use the wooden mixing stick to apply a thin coat of epoxy to side 1” of the bottom of the focus the inside curved edge of the focus tube cap as well as the out

tube.
