Product Usage Instructions

Installation
To install the TLM100, follow the steps below

1. Select a suitable location for the sensor on the tank.
2. Ensure that the tank application is compatible with TLMXXX measurement technology.

Understanding Tank Level Readings
The TLM100, TLM150, or TLM200 will transmit different readings based on the tank level. Here are the different readings and their meanings:

Dash (-)

• The level is beyond the maximum allowed range.
• The sensor signal is degraded or deflected by an object.
• Fluid is in contact with the sensor.

100%

• The level is at the minimum allowed range.
• The level is within the minimum allowed range.
• There is no level, and the tank depth exceeds the range of the device.

Erratic Readings

• The tank level table has duplicate distance entries equaling the same percentage output.
• Foam is present on the surface of the liquid.
• Tank Baffle Foam (cube form) is installed within the tank.

FAQ (Frequently Asked Questions)

• Q: I have installed the TLM100 and see incorrect tank levels; what does this mean?
  A: If you have installed a TLMXXX and are experiencing unexpected results, it may be due to the following reasons:

  • The tank application is not compatible with the TLMXXX measurement technology.
  • The tank level table has duplicate distance entries equaling the same percentage output.
  • Foam is present on the surface of the liquid.
  • Tank Baffle Foam (cube form) is installed within the tank.

• We recommend checking these factors and ensuring proper installation for accurate tank level readings.

Article Number: 535 | Rating: Unrated | Last Updated: Tue, Jul 28, 2015 8:48 PM The TLM100 uses an ultrasonic signal to determine a distance measurement from sensor to level.
The tank application must be compatible with the TLMXXX measurement technology. If you have already installed a TLMXXX and received unexpected results, the following entries may shed light on the issue.

The range for the TLMXXX modules are as follows

• TLM100 2″ to 40″
• TLM150 2″ to 24″
• TLM200 6″ to 104″

The TLM100,TLM150, or TLM200 will transmit a dash if

• Level is beyond the maximum allowed range
• Sensor signal is degraded or deflected by an object
• Fluid is in contact with the sensor

The TLM100,TLM150, or TLM200 will transmit a 100% if

• Level is at the minimum allowed range
• Level is within the minimum allowed range
• There is no level and Tank depth exceeds range of the device.

The TLM100,TLM150, or TLM200 will transmit erratic readings if

• Tank level table has duplicate distance entries equaling the same percentage output.
• Foam is present on the surface of the liquid.
• Tank Baffle Foam(cube form) is installed within the tank.
