METHOD AND DEVICE FOR CALIBRATING MEASURING TRANSDUCERS OF ULTRASONIC FLOW METERS

摘要

The invention relates to a method for calibrating measuring transducers of ultrasonic flow meters according to the transit-time difference method. The object of the invention is to provide a method for calibrating the measuring transducer of ultrasonic flow meters, said calibration being able to be carried out independently of the remaining components of the meter, such as the acoustic transducers and the measuring tube. According to the invention, the measurement signals are generated through an artificial simulation of the measurement path. This allows the measuring transducer to be calibrated independent of the remaining components of the measuring apparatus, such as the measuring tube and the acoustic transducers.
