LFL11 — locating leak alarm and cable resistance
LFL11 adds a display of estimated leak location for a compatible locating cable network, with maker material mentioning up to 150 m of detection cable. Position accuracy depends on using the approved resistive LFLX11 construction, correct terminations and segment routing. LFLX10 is a non-locating two-wire sensor and cannot automatically provide distance information. Commission the display position, alarm relay and RS485 reporting by wet-testing representative points along the installed cable.
