Method and apparatus for calibrating an ultrasonic leak location

摘要

A method for ultrasonic leak location includes showing ultrasound levels measured at various measuring locations along a measuring segment in a bar diagram. An intersection of two straight lines in the bar diagram is ascertained to identify a leakage position. At least an individual ultrasound pickup is calibrated with respect to its amplification factor and/or its location error. An apparatus for ultrasonic leak location includes a number of ultrasound pickups being disposed along a measuring segment. Amplifiers and components forming an effective value connect outputs of the ultrasound pickups to a data processing system. The data processing system calibrates an individual ultrasound pickup with respect to its amplification factor and/or its location coordinate.
