Abstract
Se proporciona un método para controlar automáticamente el gasto de flujo de masa de un gas a través de un orificio a través del cual, en el uso, se arregla el flujo estrangulado para que se presente. El método utiliza una válvula electrónica ubicada corriente abajo de una fuente de gas, un oscilador piezoeléctrico en contacto con el gas corriente arriba del orificio y corriente abajo de la válvula electrónica y un sensor de temperatura. El método comprende: a) accionar el oscilador de cristal piezoeléctrico en una frecuencia resonante; b) medir la frecuencia resonante del oscilador piezoeléctrico; o) medir la temperatura del gas; y d) controlar la válvula electrónica en respuesta a la frecuencia resonante del oscilador piezoeléctrico y la temperatura del gas con el fin de regular el gasto de flujo de masa del gas a través del orificio.
