Abstract

The invention provides a method of and/or apparatus for detecting one or more interfaces in a fluid mixture. A vertical array of TDR sensor components are arranged within the mixture and each sensor is switched to a TDR transmit/receive circuit. Signals from each sensor in the array are then processed to identify the location of the interface(s). A time domain reflectometry (TDR) sensor is claimed comprising a carrier having a curved outer surface, and a pair of substantially parallel conductors mounted on said curved outer surface, said conductors being separated by insulation. An apparatus for determining an interface in a composition is claimed, said apparatus including: a plurality of TDR sensors mounted at known vertical spacings which, in use, is placed within said composition; a controller for activating each of said sensors individually; and a processing facility operable to identify, from signals from said sensors, a location of said interface, said apparatus being characterised in that each sensor includes a pair of substantially parallel conductors separated by insulation, said conductors being mounted on a curved outer surface of a carrier.
