Ultrasonic ranging in air is known as easy and cheap technique with limited accuracy. Its industrial application mostly demands a well-defined arrangement of measurement tools to guarantee correct results. On the other hand some advantages of applying ultrasound as e.g. working in dark, foggy and dusty environment creates a vital interest in this technology. There is a need of generic ultrasonic sensing and of using the potential of attainable accuracy which is exceeding significantly the common use. On base of scientific work of years, this paper tries to give an overview over the various sensor and system design elements and over techniques which can be included in setting up a generic ultrasonic system with high accuracy. Two realized systems shortly show applications of these elements: An ultrasonic sensor system for scene analysis which enables to create a picture of the environment on base of its movement, and an ultrasonic locating system which delivers device positions with high accuracy.
