Installation and Connection Installation and Connection 1. Put the mounting point gasket (included in the kit) on the Omnicomm LLS sensor measuring probe 2. Put the Omnicomm LLS-AF 4 sensor into the tank and secure it: when securing with rivets, use a rivet gun (riveter)
Calibration of the fuel tank is necessary to verify the conformity of the digital code issued by the Omnicomm LLS-AF 4 sensor to the fuel volume in a particular fuel tank. Calibration of the fuel tank is performed by filling up the tank – from empty to full, with a certain filling interval, and recording the Omnicomm LLS sensor readings in the calibration table.
