Abstract

Método y aparato para proporcionar compensacion para los datos de salida de un caudalímetro de Coriolis, en particular datos de densidad en base a uncaudalímetro de Coriolis de un unico tubo de flujo recto. La compensacion por tensiones térmicas esp roporcionada por la utilizacion de una pluralidad desensores en diversas porciones del caudalímetro. Un primer sensor está acoplado al tubo de flujo y proporciona informacion referente a la temperatura del tubode flujo. Una pluralidad de sensoresadi cionales están conectados para formar una red que tiene una salida de dos conductores. Los sensores adicionales aplicanuna senal compuesta por la salida de dos conductores de la red a los elementos electronicos del medidor. La senal de la redreprese nta la temperatura compuestade los elementos del caudalímetro que pueden causar tensiones térmicas en el tubo de flujo cuando existe un diferencial de temperatura entre el tubo de flujo yla temperatura de esta pluralidad de elementos. Loselementos a dicionales incluyen la barra de compensacion la carcasa de caudalímetro. Se proporcionacompensacion de sensibilidad por la utilizacion de un algoritmo novedoso. La densidad es medida en un caudalímetro de un unico tubo que es calibradoutilizandodos materiales de diferentes densidades mediante la utilizacion de una formula de densidad que tiene componentes no lineales que representan la desviacion dela calibracion del medidor de la calibracion lineal.
