iTLM-1 Depth Calibration
The iTLM-1 depth calibration must be performed during the process of
installing the iTLM-1 sensor device on the tank.
At the time of the device installation, the iTLM-1 needs to know the exact depth
of the fluid in the tank to perform the depth calibration for the tank level sensor.
To set the depth calibration parameter, select the Depth Cal tab at the bottom of
the screen to access the depth calibration menu shown in Figure 26 below.
Enter the current depth of the fluid in the tank in inches in the Measured Depth
field, install the iTLM-1 sensor, and hit the Set Depth Cal button. Once the
depth calibration is complete, the value “-2” appears in the Measured Depth field
to block any inadvertent changes to the calibration parameters. Luna
iMonitoring personnel use the “-1” value, which removes the depth calibration
and reports distance. This is useful when performing the distance calibration.
