Maretron TLM150 ユーザーズマニュアル

 
If a focus tube is used for a tank with a SAE J1810 5-bolt fitting, determine the depth of the 
tank at the location of the tank sensor mounting hole and use a saw 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. 
 
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 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 TLM150 sensor component on top of the adapter so that the bolt holes on 
the TLM150 sensor component line up with the bolt holes on the adapter. 
  
Place the included mounting screws through the bolt holes on the 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.
