摘要
The apparatus (18) comprises an ultrasonic wave generator device and an ultrasonic wave receiving device which are combined to form one structural unit (20). This structural unit (20) emits ultrasonic wave impulses along a sound path (30) into the interior of an electrical cell (10). The ultrasonic wave impulses are reflected by reflector (28), the electrolyte surface (32) and the base of the cell (36) and are received by the ultrasonic wave receiver. From the travel time between the emission of an ultrasonic wave impulse and the reception of the various reflections by the ultrasonic wave receiver, the electrolyte operating conditions, eg. level, temperatures and density, within the electrolyte chamber (34) can be determined. In another embodiment, (eg Fig. 3 not shown) further reflectors are introduced at various depths in the electrolyte, thus enabling the electrolyte density at various depths to be determined. IMAGE
