A monitoring assembly (20) which has a plurality of sensors (24) arranged in spaced relationship along a body (23) which may be suspended from a coded multicore cable (25) in a reservoir to monitor liquid levels therein. Each sensor (24) is connected to a respective coded core (43) of the multicore cable (25) such that any sensor (24) may be selectively coupled to remote control apparatus. The body (23) may be formed of interconnected tubular sections (29, 30), some of which (29) support stainless steel electrode assemblies (39) forming the sensors (24). |
