Abstract

PROCEDIMIENTO Y APARATO PARA INDICAR LA POSICION DE UNA VALVULA DE COMPUERTA CON CORREDERA ACCIONABLE ELECTRICAMENTE. EL PROCESO COMPRENDE LAS SIGUIENTES FASES: PRIMERA, SE PASA EL FLUIDO HIDRAULICO SALIENTE DEL ACCIONADOR HIDRAULICO A TRAVES DE UN DISPOSITIVO DE MEDICION DE VOLUMEN PARA DETERMINAR EL FLUJO DE FLUIDO, MIENTRAS QUE EL ACCIONADOR SE MUEVE DE UNA POSICION A OTRA; SEGUNDA, SE CUENTA LA LECTURA DE VOLUMEN DEL DISPOSITIVO DE MEDICION DE VOLUMEN; TERCERA, SE TRADUCE LA CUENTA A UNA SUMA CALCULADA PARA REPRESENTAR LA POSICION DE LA COMPUERTA REFRACTARIA MOVIL; Y POR ULTIMO, SE REPRESENTA DE UN FORMA VISUAL LEGIBLE DICHA POSICION.
