Abstract

Il dispositivo (18) presenta un dispositivo per la generazione di onde ultrasonore e un dispositivo per la ricezione di onde ultrasonore che sono riuniti a dare un'unità costruttiva (20). L'unità costruttiva (20) emette impulsi di onde ultrasonore lungo un percorso del suono (30) nell'interno di una batteria (10). Le onde ultrasonore attraversano la camera dell'acido (34) e vengono captate dal dispositivo per la ricezione delle onde ultrasonore. In base ai tempi trascorsi tra l'emissione di un impulso di onde ultrasonore e la sua ricezione da parte del dispositivo per la ricezione delle onde ultrasonore è possibile ricavare conclusioni per quanto riguarda gli stati di funzionamento della camera dell'acido (34), in particolare per quanto riguarda la temperatura, il livello dell'acido, la densità dell'acido e la formazione di bolle di gas.The device (18) has a device for the generation of ultrasonic waves and a device for the reception of ultrasonic waves which are brought together to give a constructive unit (20). The construction unit (20) emits pulses of ultrasound waves along a sound path (30) inside a battery (10). The ultrasonic waves pass through the acid chamber (34) and are picked up by the device for the reception of the ultrasonic waves. Based on the time elapsed between the emission of an ultrasound wave impulse and its reception by the device for the reception of ultrasound waves, it is possible to draw conclusions regarding the operating conditions of the acid chamber (34), in particularly with regard to temperature, acid level, acid density and the formation of gas bubbles.
