Abstract

See full text

A through air level measurement instrument for use in minimizing tank rattle comprises a housing and an antenna secured to the housing. A process adaptor is associated with the antenna and the housing for securing the instrument to a closed tank with the antenna directed into an interior of the closed tank. A control in the housing generates and receives a high frequency signal using an electromagnetic radiating element proximate the antenna. The control comprises an equivalent time sampling circuit including a main oscillator driving a timing circuit controlling timing between transmitted and sample pulses. A noise generator is operatively associated with the main oscillator to randomly modulate timing of the main oscillator. The control minimizes inaccuracies caused by tank rattle.
