Description
Maretron Focus Tube w/ Dead Band Eliminator | Boat Supply Store
For vessels experiencing significant pitch and roll, this Maretron SAE 5-bolt pattern focus tube with dead band eliminator is engineered to rectify limitations in Maretron's TLM100/TLM150 ultrasonic tank level monitors. It expands the permissible pitch and roll angles to 15°, a substantial increase from the standard 6° tolerance, ensuring reliable readings on non-displacement hulls. Furthermore, it eliminates the inherent 2-inch deadband of the primary sensor, allowing for accurate measurement of tank contents down to the very top, crucial for precise fuel or water inventory management.
Key Features
- Increases pitch/roll tolerance to 15° for reliable readings on dynamic vessels.
- Eliminates the 2" deadband for precise level measurement to the tank's brim.
- Maximizes usable measurement range of TLM100/TLM150 sensors.
- Enables accurate tank level monitoring on non-displacement hulls.
- Mounts the TLM sensor 2" above the tank top for unobstructed readings.
- Features the standardized SAE 5-Bolt Pattern for secure mounting.
- Ensures accurate fuel, water, or waste level data.
- Optimizes performance of Maretron ultrasonic tank level monitors.

Common Concerns Answered
What if I don't already own a Maretron TLM100 or TLM150 sensor?
This focus tube is specifically designed as an accessory to enhance the performance of compatible Maretron TLM100 or TLM150 ultrasonic tank level monitors. It requires one of these sensors to function correctly.
Is the installation complex?
Installation is rated as moderate, requiring basic mechanical aptitude for proper mounting and alignment with the tank and TLM sensor. Familiarity with NMEA 2000 networking can be beneficial for integration into a broader system.
Is the cost of this accessory justified?
For users with vessels experiencing significant pitch and roll, or those needing to measure levels very close to the top of the tank, the increased accuracy and expanded measurement range provided by this focus tube offer significant value, ensuring precise data for critical tank management.
Frequently Asked Questions
What is the purpose of the Maretron SAE 5-Bolt Pattern Focus Tube with Dead Band Eliminator?
Its purpose is to significantly improve the accuracy and operational range of Maretron TLM100/TLM150 ultrasonic tank level monitors, particularly on vessels prone to pitch and roll, by increasing angular tolerance and eliminating measurement dead zones.
How does the focus tube improve the accuracy of the TLM100/TLM150 ultrasonic tank level monitors?
It achieves this by widening the acceptable pitch and roll angles to 15° and by eliminating the sensor's default 2-inch deadband, allowing for readings closer to the tank's physical top.
What is the maximum pitch and roll angle the focus tube can handle compared to the sensor alone?
The focus tube increases the allowable pitch and roll tolerance to 15°, compared to the standard 6° tolerance of the TLM100/TLM150 sensors when used without this accessory.
How does the dead band eliminator function with this focus tube?
The dead band eliminator physically raises the TLM100/TLM150 sensor 2 inches above the top surface of the tank, thereby removing the 2-inch measurement blind spot inherent in the sensor's design.
Is this product compatible with all Maretron tank level monitors?
No, this specific focus tube is designed for compatibility with Maretron's TLM100 and TLM150 ultrasonic tank level monitors only.
