Page 5: General
TLM100 can be calibrated for irregular tank shapes so you know the true level of your tanks. The TLM100 can be mounted on tanks with a SAE J1810 5-hole mounting pattern, or to tanks using 1.5” NPT or 1.25” BSP threaded openings via available adapters. -

Custom Calibration (Section 3.4.2) 2 Installation 2.1 Unpacking the Box When unpacking the box containing the Maretron TLM100, you should find the following items: 1 – TLM100 Tank Level Monitor 1 – TLM100 Gasket 1 – Packet of Petroleum Jelly ... -
Page 7: Theory Of Operation
The TLM100 operates by directing a pulse of ultrasonic sound from the sensor component at the top of the tank down to the surface of the liquid in the tank. The TLM100 then measures the time it takes this pulse to travel down to the surface of the liquid, be reflected back up, and then be received back at the sensor component. -
Page 8: Effect Of Pitch And Roll On The Tlm100
2.3.1 Effect of Pitch and Roll on the TLM100 Assuming that the TLM100 sensor component is mounted on a flat tank top, the TLM100 will operate correctly as long as the vessel does not experience pitch and/or roll in excess of 6° for an extended period of time. -
Page 9: Use Of An Airlock On Black Water Tanks
This is a tube which mounts into the tank before the sensor and directs the ultrasonic waves down to the surface of the liquid and back. With a focus tube, the TLM100 will operate correctly as long as the vessel does not exceed 15° of pitch and/or roll for extended periods of time. -

2.4.2.1 Installation on a Tank with a SAE J1810 5-Bolt Fitting To install the TLM100 on a tank with a SAE J1850 5-bolt fitting, place the gasket over the tank fitting so that the bolt holes line up (WARNING – the gasket must be properly aligned; it only fits one way). -
Page 11: Figure 2 - Tlm100 Mounting - Sae 5-Hole Bolt Pattern
Place the gasket included with the TLM100 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 sensor component on top of the TLM100 gasket so that the bolt holes line up. -

2.4.2.3 Installation on a Tank with a SAE J1810 5-Bolt Fitting and Airlock Installation of the TLM100 on a tank with a SAE J1810 5-bolt fitting with an airlock is identical to installation with a focus tube, except that the trimming step is eliminated. Please refer to Section 0 for details of the mounting procedure. -

3.3 Configuring Tank Capacity In addition to indicating the fluid level within a tank, the TLM100 also has the ability to be configured or programmed with the attached tank’s capacity. This way, you will be able to view the tank’s capacity as well as the amount of liquid remaining anywhere on the vessel where... -
Page 17: Tank Depth Or Custom Calibration
40” (1.02m), you must program the TLM100 with the actual depth of the tank using a display product such as the Maretron DSM250 or Maretron N2KAnalyzer software. Refer to the user’s manual of the particular product that will be used for configuring the TLM100 as these manuals provide detailed instruction on configuration procedures. -
