Abstract

SE DESCRIBEN UN SISTEMA Y UN METODO DE DETECCION DE FLUJO DE FLUIDO, EN QUE SE USAN PARA MEDIR EL FLUJO DE FLUIDO UN PAR DE DISPOSITIVOS COMPENSADOS (11, 12), SENSIBLES A LA TEMPERATURA Y CALENTADOS ELECTRICAMENTE. UNO DE LOS DISPOSITIVOS (11) ESTA SITUADO EN UNA POSICION FUERA DE LA CIRCULACION DEL FLUIDO QUE SE HA DE MEDIR, PERO EN RELACION TERMICA CON EL FLUIDO DE TAL MANERA QUE EL DISPOSITIVO (11) ES AFECTADO POR LA VARIACION DE LA TEMPERATURA AMBIENTE. EL OTRO DISPOSITIVO (12) ESTA SITUADO EN EL FLUIDO CIRCULANTE QUE SE HA DE MEDIR. ASI, UN CAMBIO DEL CAUDAL DA LUGAR A UN CAMBIO DE LA RELACION DE COEFICIENTES DE DISIPACION DE LOS DISPOSITIVOS (11, 12). CIRCUITOS (17, 45) ESTAN ACOPLADOS A CADA UNO DE LOS DISPOSITIVOS (11, 12) PARA MANTENER LOS DOS DISPOSITIVOS ESENCIALMENTE A LA MISMA TEMPERATURA. UN CAMBIO DE LA RELACION DE LAS ENERGIAS DE LOS DISPOSITIVOS (11, 12) UNO CON RESPECTO A OTRO INDICAUN CAMBIO DE LA RELACION DE COEFICIENTES DE DISIPACION QUE ES INSENSIBLE A LA VARIACION DELA TEMPERATURA AMBIENTE.
