This manual outlines the rules and procedures for installation, start-up, setting and connection of fuel level sensor LLS 20230 (hereinafter - product), as well as calibration procedure for a fuel tank with an installed sensor.

The Omnicomm LLS 20230 fuel level sensor is installed on special types of equipment or on stationary fuel tanks and storages, which require equipment explosion protection and have the “0ExiaIIBT6X” explosion protection label. The LLS 20230 fuel level sensor shall operate only with the Omnicomm BIS 20240 spark protection unit, produced by Omnicomm

Recommendations for assembling LLS 20230 fuel level sensors with the length from 3 to 6m, are given in the Appendix L.
