Abstract
LA INVENCION SE REFIERE A UN SENSOR PARA DETECTAR LA VELOCIDAD DE UN MEDIO QUE FLUYE EN UNA SALIDA DE LABORATORIO. PARA DETECTAR EN UNA SALIDA DE LABORATORIO TAMBIEN LAS MAS PEQUEÑAS VELOCIDADES DEPENDIENTES DE LA DIRECCION, DEBEN ESTAR DISPUESTOS DOS TERMISTORES MONTADOS UNO DESPUES DE OTRO EN DIRECCION DE LA CORRIENTE CON DISTANCIA RECIPROCA, A TRAVES DE UNA CORRIENTE DE FLUJO DISPUESTA ENTRE LOS DOS TERMISTORES Y A TRAVES DE UN CIRCUITO CONECTADO A LOS DOS TERMISTORES, PARA LA GENERACION DE UNA SEÑAL DIFERENCIAL.
