Abstract

"MEDIçãO DE VELOCIDADE". A presente invenção refere-se a um dispositivo de medição de velocidade (1). O objetivo da referida invenção é permitir uma medição de velocidade precisa e flexível. O referido objetivo é obtido, por meio do que os componentes de emissão são transmitidos através de dois percursos diferentes (11, 12) e detectados. Uma modificação para o deslocamento de fase entre as componentes de emissão em ambos os percursos, em relação a um dispositivo não operando (1), representa uma taxa para a velocidade real do dispositivo (1) para o meio de avaliação (13). A influência de um movimento de rotação em uma modificação para o deslocamento de fase assim é impedida ou compensada. A referida invenção também se refere a um sistema, provido com um dispositivo como esse, e a um método correspondente de medição de velocidade.
