Abstract

INCLUYE UN CANAL DE MEDICION POR EL QUE FLUYE EL AIRE, QUE SE ENCUENTRA EN EL INTERIOR DE OTRO CANAL ANULAR POR EL QUE IGUALMENTE FLUYE EL AIRE. AMBOS CANALES ESTAN COLOCADOS CON SUS ABERTURAS DE DESEMBOCADURA EN EL OBJETO DE MEDICION. EN EL CANAL DE MEDICION ESTA COLOCADA UNA RUEDA DE PALETAS DE UNA ONDA DE ANEMOMETRO PARA MEDICION DEL VOLUMEN DE CORRIENTE, QUE FLUYE SIN TORSIONES DEL AIRE QUE MANA SIN INTERRUPCION DEL CANAL DE MEDICION. ADEMAS, ESTE CANAL COMPRENDE MEDIOS SENSORES PARA PERCIBIR UNA PRESION ESTATICA DOMINANTE PARA UN AJUSTE DE LA DIFERENCIA DE PRESION. EL CANAL ANULAR Y EL DE MEDICION SE AJUSTAN UNO CON OTRO, DE TAL MODO QUE LA CANTIDAD DE AIRE FLUYENTE EN EL CANAL ANULAR, ASI COMO LA VELOCIDAD DE CORRIENTE DEL AIRE, EQUIVALEN, APROXIMADAMENTE, A LA CANTIDAD DE AIRE FLUYENTE, ASI COMO A LA VELOCIDAD DE CORRIENTE DE AIRE EN EL CANAL DE MEDICION. ESTA CONSTRUCCION PERMITE QUE PUEDA ESTABLECERSE FACIL Y RAPIDAMENTE LA PERMISIBILIDAD DE PASO DE AIRE EN AMBITOS DIFERENTES DEUN OBJETO DE MEDICION QUE, DADO EL CASO, SE MUEVE LENTAMENTE, MIENTRAS EL DISPOSITIVO DE PRUEBA SE COLOCA SOLO UNILATERALMENTE EN EL OBJETO DE MEDICION Y SE MANEJA FACILMENTE Y SIN PROBLEMAS.
