Abstract
A time domain reflectometer (TDR) transducer () for determining a level () of liquid () in a container () includes a first electrode () and a second electrode portion () with a measuring volume () therebetween for receiving material () to be measured. The second electrode portion () has a shielded electrode section (A) isolated from the first electrode () and an unshielded electrode section (B), such that an energy pulse propagates along the shielded electrode section (A) without signal loss, and boomerangs along a second opposite direction across the first conductive electrode portion (), the measuring volume () and the unshielded electrode section (B) where partial reflection of the pulse occurs at least at the interface () of the material () to create a return echo that travels in reverse direction, boomeranging back through the shielded electrode section (A) for analysis by an electronic assembly ().
