Abstract
Un excitador de vibracion oscilatorio (104) está conectado operativamente a un medidor de flujo de Coriolis (10) para hacer vibrar los tubos (103A y103B) del medidor de flujo. Los elementos electronicos del medidor (20) contienen un circuito mimético (414, 802, 902) que permiten la utilizaciondel excitador como un transductor de senales que proporciona una medicion de fuerza contra electromotriz para utilizacion en el cálculo del caudal demasa y densidad en base al medidor de flujo de Coriolis. El circuito mimético contiene una bobina analogica (604) y un imán (600) que facilitan la medicion dela fuerza contra electromotriz, o el circuito mimético puede comprender elementos digitales (804, 806, 808, 904, 906). El invento incluye un métodopara el uso del aparato.
