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 operating range for the TLMXXX modules are as follows:

TLM100 2" to 40"

TLM150 2" to 24"

TLM200 6" to 104"

The TLMXXX will transmit a dash if:

Level is beyond 40" range.

Sensor signal is degraded or deflected by an object.

Fluid is in contact with the sensor.

The TLMXXX will transmit a 100% if:

Level is at the dead band limit of 2"

Level is within the 2"dead band limit

There is no level and Tank depth exceeds range of the device.

The TLMXXX 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.
